Keyboard accessibility benefits many people, including those with disabilities, who may find it difficult or impossible to use a mouse. It also helps power users who prefer the efficiency of keyboard shortcuts. In this article, we’ll explore how to make your website fully keyboard accessible, ensuring that everyone can use your site easily and effectively.
Understanding Keyboard Accessibility
The Importance of Keyboard Accessibility
Keyboard accessibility isn’t just a nice-to-have feature; it’s a must for creating an inclusive online environment. When your website is fully accessible by keyboard, you make it possible for people with a wide range of disabilities to access your content.
This includes individuals with motor disabilities, who may not be able to use a mouse, as well as those who are blind or have low vision and rely on screen readers.
By ensuring your website is keyboard accessible, you’re not only complying with legal requirements and accessibility standards but also showing your commitment to inclusivity and user experience.
Basic Concepts of Keyboard Navigation
To make your website keyboard accessible, you need to understand the basic concepts of keyboard navigation:
- Tabbing: Users should be able to navigate through all interactive elements (like links, buttons, and form fields) using the Tab key. The focus should move in a logical order that follows the visual flow of the page.
- Focus: When an element is focused, it should be visibly highlighted so users know where they are on the page. This is typically indicated by a border or a background color change.
- Keyboard Shortcuts: Providing keyboard shortcuts for frequently used actions can greatly enhance the user experience. However, these shortcuts should not interfere with the standard browser or screen reader shortcuts.
Step-by-Step Guide to Making Your Website Keyboard Accessible
Audit Your Current Website
Before making any changes, it’s essential to understand the current state of your website’s keyboard accessibility. Conduct a thorough audit to identify any issues.
You can do this manually by trying to navigate your site using only the keyboard, or you can use automated tools like WAVE, Axe, or Lighthouse to help identify problems.
Ensure All Interactive Elements Are Keyboard Accessible
Links and Buttons
All links and buttons on your website should be accessible via the keyboard. This means users should be able to tab to these elements and activate them using the Enter or Space keys. Make sure that custom elements, such as those created with JavaScript, also follow these rules.
<a href="#example">Example Link</a>
<button>Example Button</button>
Forms
Form fields should be navigable using the Tab key, and each field should be clearly labeled. This helps users understand what information is required in each field. Use the label
element to associate labels with their corresponding input fields.
<label for="name">Name:</label>
<input type="text" id="name" name="name">
Menus
Dropdown and navigation menus should be fully accessible via the keyboard. Users should be able to open and close menus, navigate through menu items, and select options using the keyboard.
<nav>
<ul>
<li><a href="#home">Home</a></li>
<li><a href="#about">About</a></li>
<li><a href="#contact">Contact</a></li>
</ul>
</nav>
Enhancing Focus Visibility
Default Focus Styles
Browsers provide default focus styles, but these might not always be sufficient. Enhance the visibility of focused elements by customizing the focus styles using CSS. Ensure that the focus indicator is distinct and clearly visible.
a:focus,
button:focus {
outline: 2px solid #000; /* or any other visible style */
}
Skip to Content Links
Provide a “Skip to Content” link at the top of your pages to allow users to bypass repetitive navigation links and go directly to the main content. This improves the user experience, especially for those who rely on keyboard navigation.
<a href="#main-content" class="skip-link">Skip to Content</a>
.skip-link {
position: absolute;
top: -40px;
left: 0;
background: #000;
color: #fff;
padding: 8px;
z-index: 100;
}
.skip-link:focus {
top: 0;
}

Accessible Rich Internet Applications (ARIA) is a set of attributes that can be added to HTML elements to make web content more accessible. ARIA roles and properties provide additional information to assistive technologies, such as screen readers, which can be especially useful for complex web applications.
Here are some key ARIA roles and properties that can enhance keyboard accessibility:
ARIA Roles
- Role=”button”: Use this role to indicate that a non-button element (such as a div or span) functions as a button.
- Role=”navigation”: This role helps identify a section of the page intended for navigation.
- Role=”dialog”: Use this role for modal dialogs to help screen readers identify and interact with them correctly.
<div role="button" tabindex="0">Clickable Div</div>
<nav role="navigation">...</nav>
<div role="dialog" aria-labelledby="dialog-title" aria-describedby="dialog-description">...</div>
ARIA Properties
- aria-label: Provides an accessible name for an element when the visible text isn’t sufficient.
- aria-labelledby: Identifies the element that labels the current element.
- aria-describedby: Provides additional descriptive information for an element.
<button aria-label="Close">X</button>
<div id="dialog-title">Dialog Title</div>
<div id="dialog-description">Dialog description text.</div>
Handling Complex Components
Modal Dialogs
Making modal dialogs accessible can be challenging but is essential for keyboard navigation. Here are some tips:
- Focus Management: When the modal opens, focus should move to the first focusable element inside the modal. When the modal closes, focus should return to the element that triggered the modal.
- Keyboard Traps: Ensure focus does not leave the modal while it is open.
<!-- Example of a modal dialog -->
<div role="dialog" aria-labelledby="modal-title" aria-hidden="true">
<h2 id="modal-title">Modal Title</h2>
<button aria-label="Close">Close</button>
</div>
Dropdown Menus
Dropdown menus should be fully navigable using the keyboard. Users should be able to open the menu, navigate through the options, and select an option using the keyboard.
- Focus Management: Focus should move to the first menu item when the dropdown is opened.
- Close on Escape: The dropdown should close when the Escape key is pressed.
<!-- Example of a dropdown menu -->
<div role="menu">
<button aria-haspopup="true">Menu</button>
<ul>
<li role="menuitem">Option 1</li>
<li role="menuitem">Option 2</li>
