Advanced CSS Techniques for Designing Custom Tooltips

Tooltips are essential for providing additional information without cluttering a web page. They appear when a user hovers over an element, offering contextual help or explanations. While tooltips may seem simple, designing custom tooltips using advanced CSS techniques can significantly enhance user experience. In this article, we’ll explore various CSS methods to create engaging and effective custom tooltips. We’ll cover everything from basic styles to advanced animations and interactive tooltips.

Understanding the Basics of Tooltips

What Are Tooltips?

Tooltips are small, hover-activated pop-ups that provide additional information about an element. They can be used to explain icons, buttons, links, and more.

Tooltips improve usability by giving users more context without overwhelming them with text.

Why Use Custom Tooltips?

Custom tooltips allow you to match the look and feel of your website, providing a cohesive user experience. Unlike default browser tooltips, custom tooltips can be styled and animated to enhance visual appeal and engagement.

Basic Tooltip Design

Simple Tooltip with CSS

Creating a basic tooltip involves using the :hover pseudo-class to display additional content when the user hovers over an element.

<div class="tooltip-container">
    Hover over me
    <span class="tooltip-text">This is a tooltip</span>
</div>

.tooltip-container {
    position: relative;
    display: inline-block;
    cursor: pointer;
}

.tooltip-text {
    visibility: hidden;
    width: 120px;
    background-color: black;
    color: white;
    text-align: center;
    border-radius: 5px;
    padding: 5px 0;
    position: absolute;
    z-index: 1;
    bottom: 125%; /* Position the tooltip above the text */
    left: 50%;
    margin-left: -60px;
    opacity: 0;
    transition: opacity 0.3s;
}

.tooltip-container:hover .tooltip-text {
    visibility: visible;
    opacity: 1;
}

In this example, the tooltip appears above the text when the user hovers over the container.

Positioning Tooltips

Top, Bottom, Left, and Right Positioning

Tooltips can be positioned in various places relative to the hovered element. Here’s how you can position tooltips at the top, bottom, left, and right.

<div class="tooltip-container top">
    Top Tooltip
    <span class="tooltip-text">Tooltip at the top</span>
</div>
<div class="tooltip-container bottom">
    Bottom Tooltip
    <span class="tooltip-text">Tooltip at the bottom</span>
</div>
<div class="tooltip-container left">
    Left Tooltip
    <span class="tooltip-text">Tooltip on the left</span>
</div>
<div class="tooltip-container right">
    Right Tooltip
    <span class="tooltip-text">Tooltip on the right</span>
</div>

.tooltip-container {
    position: relative;
    display: inline-block;
    cursor: pointer;
}

.tooltip-text {
    visibility: hidden;
    background-color: black;
    color: white;
    text-align: center;
    border-radius: 5px;
    padding: 5px 0;
    position: absolute;
    z-index: 1;
    opacity: 0;
    transition: opacity 0.3s;
}

.tooltip-container.top .tooltip-text {
    bottom: 125%;
    left: 50%;
    margin-left: -60px;
}

.tooltip-container.bottom .tooltip-text {
    top: 125%;
    left: 50%;
    margin-left: -60px;
}

.tooltip-container.left .tooltip-text {
    top: -5px;
    right: 105%;
}

.tooltip-container.right .tooltip-text {
    top: -5px;
    left: 105%;
}

.tooltip-container:hover .tooltip-text {
    visibility: visible;
    opacity: 1;
}

Styling Tooltips

Customizing Tooltip Appearance

Customizing the appearance of tooltips can help them blend seamlessly with your website’s design. You can change colors, fonts, sizes, and add shadows to make them more appealing.

.tooltip-text {
    visibility: hidden;
    width: 140px;
    background-color: #333;
    color: #fff;
    text-align: center;
    border-radius: 6px;
    padding: 8px 0;
    position: absolute;
    z-index: 1;
    bottom: 125%;
    left: 50%;
    margin-left: -70px;
    opacity: 0;
    transition: opacity 0.3s, transform 0.3s;
    font-family: 'Arial', sans-serif;
    font-size: 14px;
    box-shadow: 0 5px 10px rgba(0, 0, 0, 0.2);
}

.tooltip-container:hover .tooltip-text {
    visibility: visible;
    opacity: 1;
    transform: translateY(-5px);
}

Advanced Tooltip Techniques

Adding Arrows to Tooltips

Adding arrows to tooltips can enhance their appearance and make it clearer what the tooltip is referring to. This involves using pseudo-elements to create the arrow shapes.

.tooltip-text::after {
    content: '';
    position: absolute;
    top: 100%;
    left: 50%;
    margin-left: -5px;
    border-width: 5px;
    border-style: solid;
    border-color: black transparent transparent transparent;
}

By using the ::after pseudo-element, we can add a small arrow to the bottom of the tooltip that points to the text it describes.

Animated Tooltips

Animating tooltips can make them more engaging. You can use CSS animations to create effects such as fading, sliding, or scaling.

.tooltip-container:hover .tooltip-text {
    visibility: visible;
    opacity: 1;
    animation: fadeIn 0.3s ease-in-out;
}

@keyframes fadeIn {
    from {
        opacity: 0;
        transform: translateY(10px);
    }
    to {
        opacity: 1;
        transform: translateY(0);
    }
}

This example uses a fade-in animation to make the tooltip smoothly appear when the user hovers over the element.

Interactive Tooltip Techniques

Tooltips with CSS Transitions

CSS transitions can add smooth, elegant animations to your tooltips, enhancing the user experience.

Fade-In and Slide-Up Tooltip

This effect combines a fade-in and slide-up animation for a more dynamic tooltip appearance.

.tooltip-container:hover .tooltip-text {
    visibility: visible;
    opacity: 1;
    transform: translateY(-10px);
    transition: opacity 0.3s ease-in-out, transform 0.3s ease-in-out;
}

.tooltip-text {
    transform: translateY(0);
}

Animated Tooltips with Keyframes

Using CSS keyframes, you can create more complex animations for your tooltips.

Bounce Animation

A bounce animation can make tooltips stand out and draw the user’s attention effectively.

.tooltip-container:hover .tooltip-text {
    visibility: visible;
    opacity: 1;
    animation: bounceIn 0.6s;
}

@keyframes bounceIn {
    0%, 20%, 40%, 60%, 80%, 100% {
        -webkit-transform: translateY(0);
        transform: translateY(0);
    }
    50% {
        -webkit-transform: translateY(-10px);
        transform: translateY(-10px);
    }
}

Advanced Interactive Tooltips

Tooltips with Input Fields

Tooltips can include input fields for dynamic interaction, such as quick forms or search boxes.

<div class="tooltip-container">
    Click me
    <div class="tooltip-text">
        <input type="text" placeholder="Search...">
        <button type="button">Go</button>
    </div>
</div>

.tooltip-container {
    position: relative;
    display: inline-block;
    cursor: pointer;
}

.tooltip-text {
    visibility: hidden;
    width: 200px;
    background-color: #333;
    color: #fff;
    text-align: center;
    border-radius: 6px;
    padding: 10px;
    position: absolute;
    z-index: 1;
    bottom: 125%;
    left: 50%;
    margin-left: -100px;
    opacity: 0;
    transition: opacity 0.3s, transform 0.3s;
    font-family: 'Arial', sans-serif;
    box-shadow: 0 5px 10px rgba(0, 0, 0, 0.2);
}

.tooltip-text input {
    width: 80%;
    padding: 5px;
    margin-bottom: 5px;
    border-radius: 3px;
    border: none;
}

.tooltip-text button {
    padding: 5px 10px;
    border: none;
    border-radius: 3px;
    background-color: #00ff00;
    color: white;
}

.tooltip-container:hover .tooltip-text {
    visibility: visible;
    opacity: 1;
    transform: translateY(-5px);
}

Tooltips with Media Content

Tooltips can also display media content such as videos or images for a richer user experience.

<div class="tooltip-container">
    Hover over me
    <div class="tooltip-text">
        <img src="thumbnail.jpg" alt="Image">
        <p>Watch this video:</p>
        <iframe src="https://www.youtube.com/embed/dQw4w9WgXcQ" frameborder="0" allowfullscreen></iframe>
    </div>
</div>

.tooltip-container {
    position: relative;
    display: inline-block;
    cursor: pointer;
}

.tooltip-text {
    visibility: hidden;
    width: 300px;
    background-color: #333;
    color: #fff;
    text-align: center;
    border-radius: 6px;
    padding: 10px;
    position: absolute;
    z-index: 1;
    bottom: 125%;
    left: 50%;
    margin-left: -150px;
    opacity: 0;
    transition: opacity 0.3s, transform 0.3s;
    font-family: 'Arial', sans-serif;
    box-shadow: 0 5px 10px rgba(0, 0, 0, 0.2);
}

.tooltip-text img {
    width: 100%;
    border-radius: 4px;
    margin-bottom: 10px;
}

.tooltip-text iframe {
    width: 100%;
    border-radius: 4px;
}

.tooltip-container:hover .tooltip-text {
    visibility: visible;
    opacity: 1;
    transform: translateY(-5px);
}

Practical Implementations

Tooltips in Data Visualization

Tooltips can be particularly useful in data visualization to provide more information about data points.

<div class="chart-point tooltip-container">
    Data Point
    <div class="tooltip-text">
        <strong>Data:</strong> 150<br>
        <strong>Category:</strong> Sales
    </div>
</div>

.chart-point {
    position: relative;
    display: inline-block;
    cursor: pointer;
    margin: 20px;
}

.tooltip-text {
    visibility: hidden;
    width: 120px;
    background-color: #333;
    color: #fff;
    text-align: center;
    border-radius: 6px;
    padding: 10px;
    position: absolute;
    z-index: 1;
    bottom: 125%;
    left: 50%;
    margin-left: -60px;
    opacity: 0;
    transition: opacity 0.3s, transform 0.3s;
    font-family: 'Arial', sans-serif;
    box-shadow: 0 5px 10px rgba(0, 0, 0, 0.2);
}

.chart-point:hover .tooltip-text {
    visibility: visible;
    opacity: 1;
    transform: translateY(-5px);
}

Tooltips for Interactive Infographics

Interactive infographics can use tooltips to provide detailed information about specific sections.

<div class="infographic-section tooltip-container">
    Section Info
    <div class="tooltip-text">
        <p>Detailed information about this section of the infographic.</p>
    </div>
</div>

.infographic-section {
    position: relative;
    display: inline-block;
    cursor: pointer;
    margin: 20px;
}

.tooltip-text {
    visibility: hidden;
    width: 200px;
    background-color: #333;
    color: #fff;
    text-align: center;
    border-radius: 6px;
    padding: 10px;
    position: absolute;
    z-index: 1;
    bottom: 125%;
    left: 50%;
    margin-left: -100px;
    opacity: 0;
    transition: opacity 0.3s, transform 0.3s;
    font-family: 'Arial', sans-serif;
    box-shadow: 0 5px 10px rgba(0, 0, 0, 0.2);
}

.infographic-section:hover .tooltip-text {
    visibility: visible;
    opacity: 1;
    transform: translateY(-5px);
}

Interactive and Advanced Tooltip Techniques

Tooltips with Delayed Appearance

Adding a delay to tooltips can prevent them from appearing too quickly, which can be helpful in improving user experience.

.tooltip-container:hover .tooltip-text {
    visibility: visible;
    opacity: 1;
    animation: fadeIn 0.3s ease-in-out 0.5s; /* 0.5s delay */
}

The animation property now includes a delay, which makes the tooltip appear 0.5 seconds after the user hovers over the element.

Responsive Tooltips

Ensuring tooltips are responsive and work well on various devices is crucial. You can use media queries to adjust the tooltip styling for different screen sizes.

@media (max-width: 600px) {
    .tooltip-text {
        width: 100px;
        font-size: 12px;
    }
}

This media query reduces the width and font size of the tooltip for smaller screens, ensuring it remains readable.

Interactive Tooltips with CSS

Tooltip with Image

You can enhance tooltips by including images, making them more informative and engaging.

<div class="tooltip-container">
    Hover over me
    <div class="tooltip-text">
        <img src="image.jpg" alt="Sample Image">
        <p>This is a tooltip with an image.</p>
    </div>
</div>

.tooltip-text {
    visibility: hidden;
    width: 200px;
    background-color: #333;
    color: #fff;
    text-align: center;
    border-radius: 6px;
    padding: 10px;
    position: absolute;
    z-index: 1;
    bottom: 125%;
    left: 50%;
    margin-left: -100px;
    opacity: 0;
    transition: opacity 0.3s, transform 0.3s;
    font-family: 'Arial', sans-serif;
    box-shadow: 0 5px 10px rgba(0, 0, 0, 0.2);
}

.tooltip-text img {
    width: 100%;
    border-radius: 4px;
}

.tooltip-container:hover .tooltip-text {
    visibility: visible;
    opacity: 1;
    transform: translateY(-5px);
}

Advanced Animations and Interactions

Sliding Tooltips

Sliding tooltips provide a dynamic visual effect that can make your website feel more interactive.

.tooltip-container:hover .tooltip-text {
    visibility: visible;
    opacity: 1;
    animation: slideIn 0.3s ease-in-out;
}

@keyframes slideIn {
    from {
        transform: translateY(-10px);
        opacity: 0;
    }
    to {
        transform: translateY(0);
        opacity: 1;
    }
}

The slide-in animation makes the tooltip appear from above with a smooth transition.

Tooltip with Interactive Content

Tooltips can also include interactive content such as links or buttons, making them more functional.

<div class="tooltip-container">
    Hover over me
    <div class="tooltip-text">
        <p>Learn more about this topic:</p>
        <a href="#">Click here</a>
    </div>
</div>

.tooltip-text {
    visibility: hidden;
    width: 200px;
    background-color: #333;
    color: #fff;
    text-align: center;
    border-radius: 6px;
    padding: 10px;
    position: absolute;
    z-index: 1;
    bottom: 125%;
    left: 50%;
    margin-left: -100px;
    opacity: 0;
    transition: opacity 0.3s, transform 0.3s;
    font-family: 'Arial', sans-serif;
    box-shadow: 0 5px 10px rgba(0, 0, 0, 0.2);
}

.tooltip-text a {
    color: #00ff00;
    text-decoration: none;
}

.tooltip-text a:hover {
    text-decoration: underline;
}

.tooltip-container:hover .tooltip-text {
    visibility: visible;
    opacity: 1;
    transform: translateY(-5px);
}

Tooltip Accessibility

Accessible Tooltips

Ensuring tooltips are accessible to all users, including those using screen readers, is crucial. Use ARIA attributes to make your tooltips more accessible.

<div class="tooltip-container" aria-describedby="tooltip1">
    Hover over me
    <div class="tooltip-text" role="tooltip" id="tooltip1">This is an accessible tooltip</div>
</div>

Using aria-describedby and role="tooltip" makes the tooltip content available to screen readers.

Practical Applications

Tooltips in Forms

Tooltips can be very useful in forms, providing additional information or guidance for filling out fields.

<div class="form-group tooltip-container">
    <label for="email">Email:</label>
    <input type="email" id="email" name="email">
    <span class="tooltip-text">Please enter your email address.</span>
</div>

.form-group {
    position: relative;
}

.form-group .tooltip-text {
    bottom: 150%;
    left: 50%;
    margin-left: -60px;
}

Tooltips for Navigation

Tooltips can enhance navigation menus by providing additional context or information about menu items.

<nav>
    <ul>
        <li class="tooltip-container">
            <a href="#">Home</a>
            <span class="tooltip-text">Go to homepage</span>
        </li>
        <li class="tooltip-container">
            <a href="#">About</a>
            <span class="tooltip-text">Learn more about us</span>
        </li>
        <li class="tooltip-container">
            <a href="#">Contact</a>
            <span class="tooltip-text">Get in touch</span>
        </li>
    </ul>
</nav>

nav ul {
    list-style: none;
    padding: 0;
}

nav li {
    display: inline-block;
    position: relative;
    margin-right: 20px;
}

nav li .tooltip-text {
    bottom: 100%;
    left: 50%;
    margin-left: -60px;
}

Enhancing Tooltip Functionality

Persistent Tooltips

Persistent tooltips remain visible even when the user moves the cursor away from the element. This can be useful for providing more detailed information without requiring constant hovering.

<div class="tooltip-container">
    Hover over me
    <div class="tooltip-text">
        <p>This tooltip remains visible when you move your cursor away.</p>
    </div>
</div>

.tooltip-container {
    position: relative;
    display: inline-block;
    cursor: pointer;
}

.tooltip-text {
    visibility: hidden;
    width: 200px;
    background-color: #333;
    color: #fff;
    text-align: center;
    border-radius: 6px;
    padding: 10px;
    position: absolute;
    z-index: 1;
    bottom: 125%;
    left: 50%;
    margin-left: -100px;
    opacity: 0;
    transition: opacity 0.3s, transform 0.3s;
    font-family: 'Arial', sans-serif;
    box-shadow: 0 5px 10px rgba(0, 0, 0, 0.2);
}

.tooltip-container:hover .tooltip-text {
    visibility: visible;
    opacity: 1;
    transform: translateY(-5px);
}

.tooltip-container:hover .tooltip-text:hover {
    visibility: visible;
    opacity: 1;
}

Tooltips with Dynamic Content

Tooltips can display dynamic content, such as data fetched from a server or generated based on user input.

<div class="tooltip-container">
    Hover over me
    <div class="tooltip-text">
        <p id="dynamic-content">Loading...</p>
    </div>
</div>

.tooltip-container {
    position: relative;
    display: inline-block;
    cursor: pointer;
}

.tooltip-text {
    visibility: hidden;
    width: 200px;
    background-color: #333;
    color: #fff;
    text-align: center;
    border-radius: 6px;
    padding: 10px;
    position: absolute;
    z-index: 1;
    bottom: 125%;
    left: 50%;
    margin-left: -100px;
    opacity: 0;
    transition: opacity 0.3s, transform 0.3s;
    font-family: 'Arial', sans-serif;
    box-shadow: 0 5px 10px rgba(0, 0, 0, 0.2);
}

.tooltip-container:hover .tooltip-text {
    visibility: visible;
    opacity: 1;
    transform: translateY(-5px);
}

document.querySelector('.tooltip-container').addEventListener('mouseover', function() {
    document.getElementById('dynamic-content').textContent = 'Dynamic content loaded!';
});

Complex Tooltip Designs

Tooltips with Tabs

Creating tooltips with tabbed content can provide more structured and detailed information.

<div class="tooltip-container">
    Hover over me
    <div class="tooltip-text">
        <div class="tabs">
            <div class="tab active" data-tab="tab1">Tab 1</div>
            <div class="tab" data-tab="tab2">Tab 2</div>
        </div>
        <div class="tab-content" id="tab1">Content for Tab 1</div>
        <div class="tab-content" id="tab2" style="display:none;">Content for Tab 2</div>
    </div>
</div>

.tooltip-container {
    position: relative;
    display: inline-block;
    cursor: pointer;
}

.tooltip-text {
    visibility: hidden;
    width: 300px;
    background-color: #333;
    color: #fff;
    text-align: center;
    border-radius: 6px;
    padding: 10px;
    position: absolute;
    z-index: 1;
    bottom: 125%;
    left: 50%;
    margin-left: -150px;
    opacity: 0;
    transition: opacity 0.3s, transform 0.3s;
    font-family: 'Arial', sans-serif;
    box-shadow: 0 5px 10px rgba(0, 0, 0, 0.2);
}

.tabs {
    display: flex;
    justify-content: space-around;
    margin-bottom: 10px;
}

.tab {
    cursor: pointer;
    padding: 5px 10px;
    background-color: #444;
    border-radius: 3px;
}

.tab.active {
    background-color: #666;
}

.tab-content {
    display: none;
}

.tab-content.active {
    display: block;
}

.tooltip-container:hover .tooltip-text {
    visibility: visible;
    opacity: 1;
    transform: translateY(-5px);
}

document.querySelectorAll('.tab').forEach(function(tab) {
    tab.addEventListener('click', function() {
        document.querySelectorAll('.tab').forEach(function(tab) {
            tab.classList.remove('active');
        });
        document.querySelectorAll('.tab-content').forEach(function(content) {
            content.classList.remove('active');
        });
        document.getElementById(this.dataset.tab).classList.add('active');
        this.classList.add('active');
    });
});

Enhancing Performance

Using Hardware Acceleration

Enhancing Tooltips with Modern CSS Techniques

Using CSS Grid for Layout

CSS Grid can be used to create sophisticated layouts within tooltips, making them more informative and visually appealing.

<div class="tooltip-container">
    Hover over me
    <div class="tooltip-text">
        <div class="grid-layout">
            <div class="grid-item">
                <img src="icon1.png" alt="Icon 1">
                <p>Feature 1</p>
            </div>
            <div class="grid-item">
                <img src="icon2.png" alt="Icon 2">
                <p>Feature 2</p>
            </div>
            <div class="grid-item">
                <img src="icon3.png" alt="Icon 3">
                <p>Feature 3</p>
            </div>
            <div class="grid-item">
                <img src="icon4.png" alt="Icon 4">
                <p>Feature 4</p>
            </div>
        </div>
    </div>
</div>

.tooltip-container {
    position: relative;
    display: inline-block;
    cursor: pointer;
}

.tooltip-text {
    visibility: hidden;
    width: 300px;
    background-color: #333;
    color: #fff;
    text-align: center;
    border-radius: 6px;
    padding: 10px;
    position: absolute;
    z-index: 1;
    bottom: 125%;
    left: 50%;
    margin-left: -150px;
    opacity: 0;
    transition: opacity 0.3s, transform 0.3s;
    font-family: 'Arial', sans-serif;
    box-shadow: 0 5px 10px rgba(0, 0, 0, 0.2);
}

.grid-layout {
    display: grid;
    grid-template-columns: repeat(2, 1fr);
    gap: 10px;
}

.grid-item {
    display: flex;
    flex-direction: column;
    align-items: center;
}

.grid-item img {
    width: 40px;
    height: 40px;
    margin-bottom: 5px;
}

.tooltip-container:hover .tooltip-text {
    visibility: visible;
    opacity: 1;
    transform: translateY(-5px);
}

Advanced CSS Techniques

CSS Variables for Themeable Tooltips

CSS variables allow you to create themeable tooltips that can be easily adjusted site-wide by changing variable values.

:root {
    --tooltip-bg: #333;
    --tooltip-color: #fff;
    --tooltip-padding: 10px;
    --tooltip-radius: 6px;
}

.tooltip-container {
    position: relative;
    display: inline-block;
    cursor: pointer;
}

.tooltip-text {
    visibility: hidden;
    width: 200px;
    background-color: var(--tooltip-bg);
    color: var(--tooltip-color);
    text-align: center;
    border-radius: var(--tooltip-radius);
    padding: var(--tooltip-padding);
    position: absolute;
    z-index: 1;
    bottom: 125%;
    left: 50%;
    margin-left: -100px;
    opacity: 0;
    transition: opacity 0.3s, transform 0.3s;
    font-family: 'Arial', sans-serif;
    box-shadow: 0 5px 10px rgba(0, 0, 0, 0.2);
}

.tooltip-container:hover .tooltip-text {
    visibility: visible;
    opacity: 1;
    transform: translateY(-5px);
}

Changing the values of --tooltip-bg, --tooltip-color, and other variables allows you to quickly adjust the look and feel of your tooltips.

Tooltips with SVG Animations

Animated SVG Tooltips

SVGs can be used within tooltips to create detailed and animated graphics, making the tooltips more interactive.

<div class="tooltip-container">
    Hover over me
    <div class="tooltip-text">
        <svg width="100" height="100">
            <circle cx="50" cy="50" r="40" stroke="green" stroke-width="4" fill="yellow" />
            <animate attributeName="r" from="40" to="20" dur="0.5s" begin="mouseover" end="mouseout" fill="freeze"/>
        </svg>
        <p>SVG animation on hover.</p>
    </div>
</div>

.tooltip-container {
    position: relative;
    display: inline-block;
    cursor: pointer;
}

.tooltip-text {
    visibility: hidden;
    width: 220px;
    background-color: #333;
    color: #fff;
    text-align: center;
    border-radius: 6px;
    padding: 10px;
    position: absolute;
    z-index: 1;
    bottom: 125%;
    left: 50%;
    margin-left: -110px;
    opacity: 0;
    transition: opacity 0.3s, transform 0.3s;
    font-family: 'Arial', sans-serif;
    box-shadow: 0 5px 10px rgba(0, 0, 0, 0.2);
}

.tooltip-container:hover .tooltip-text {
    visibility: visible;
    opacity: 1;
    transform: translateY(-5px);
}

Responsive Tooltips

Media Queries for Responsive Design

Ensure that your tooltips look good on different devices by using media queries.

@media (max-width: 768px) {
    .tooltip-text {
        width: 150px;
        font-size: 14px;
        padding: 8px;
    }
}

@media (max-width: 480px) {
    .tooltip-text {
        width: 120px;
        font-size: 12px;
        padding: 6px;
    }
}

Tooltips for Different Use Cases

Tooltips in Maps

Tooltips can provide detailed information about locations on a map.

<div class="map-point tooltip-container">
    <img src="map-point-icon.png" alt="Map Point">
    <div class="tooltip-text">
        <p>Location: Central Park</p>
        <p>Description: A large public park in New York City.</p>
    </div>
</div>

.map-point {
    position: relative;
    display: inline-block;
}

.map-point img {
    width: 40px;
    height: 40px;
}

.tooltip-container:hover .tooltip-text {
    visibility: visible;
    opacity: 1;
    transform: translateY(-5px);
}

Tooltips for Interactive Charts

Interactive charts can use tooltips to display additional data about specific points.

<div class="chart-point tooltip-container">
    <div class="point" style="height: 100px; width: 20px; background: blue;"></div>
    <div class="tooltip-text">
        <p>Data Point: 100</p>
        <p>Description: This point represents 100 units.</p>
    </div>
</div>

.chart-point {
    position: relative;
    display: inline-block;
    margin: 10px;
}

.tooltip-container:hover .tooltip-text {
    visibility: visible;
    opacity: 1;
    transform: translateY(-5px);
}

Accessibility Considerations

ARIA Roles and Properties

Use ARIA roles and properties to ensure that tooltips are accessible to users with disabilities.

<div class="tooltip-container" aria-describedby="tooltip1">
    Hover over me
    <div class="tooltip-text" role="tooltip" id="tooltip1">This is an accessible tooltip</div>
</div>

Using aria-describedby and role="tooltip" makes the tooltip content available to screen readers, improving accessibility.
