Text Content Best Practices

Creating accessible website text starts with a clear structure and straightforward language. This involves focusing on two main areas: using simple, direct text and organizing headings logically. Here's how to make these work effectively.

Write Simple, Direct Text

Keep your sentences short and to the point. Use everyday language and break down complicated ideas into smaller, easier-to-understand pieces. This approach improves readability for everyone.

Set Up Proper Heading Structure

Headings provide a roadmap for users and screen readers. Start with an H1 for the main title, use H2 for major sections, and organize subsections with H3 through H6 as needed. Always follow the correct order - don’t skip levels - to keep the content flow consistent.

Making Videos and Audio Accessible

Ensuring your multimedia content is accessible allows everyone to engage with it. Below are some practical tips to make your videos and audio more user-friendly.

Video Caption Guidelines

When adding captions to your videos, keep these points in mind:

Sync captions accurately with the audio.
Clearly identify speakers, especially when multiple voices are present.
Briefly describe important sound effects (e.g., [applause] or [door slams]).
Use high-contrast text for captions to ensure readability and position them so they don't block essential visuals.

Create Content Transcripts

Providing text transcripts ensures everyone can access your content, even without audio or video. A good transcript should include:

An exact record of spoken words.
Speaker identification.
Notes on non-speech sounds.
Descriptions of key visuals in video content.
Timestamps for easier navigation, especially for longer content.

Place transcripts near the media player or in an easy-to-find spot. For lengthy content, consider using a collapsible section to keep the layout clean.

Pick media players that work well with accessibility tools. Look for these features:

Full keyboard control for playback functions, with clear focus indicators and good contrast.
Properly labeled controls using ARIA attributes.
Adjustable playback speed options.
Independent volume controls.
Support for common caption formats like WebVTT.

As an alternative, provide direct download links to media files (e.g., MP3, MP4, WebM) along with the transcripts to ensure accessibility for all users.

Ensuring your website's navigation is easy to use helps all users move through your content smoothly. Here's how to set up navigation that works for everyone.

Make sure your site supports full keyboard navigation with clear focus indicators that are easy to see. The following keys are essential:

Tab: Moves focus between elements
Enter: Activates selected items
Space: Toggles controls
Arrow keys: Navigate within components

Regularly test your site to avoid keyboard traps and confirm navigation feels natural and intuitive.

Add Content Skip Links

Skip links allow users to bypass repetitive navigation and jump straight to the main content. Place these links at the top of your page, ensuring they become visible when focused via the keyboard. Common destinations for skip links include:

Main content
Navigation menu
Search bar
Footer

Use straightforward, action-oriented text like "Skip to main content" or "Jump to navigation" to make their purpose clear.

Page Layout and ARIA Tags

Organize your page layout consistently and use ARIA (Accessible Rich Internet Applications) tags to help screen readers interpret your site’s structure. Key ARIA roles include:

role="banner": For the header
role="navigation": For menus
role="main": For primary content
role="complementary": For sidebars
role="contentinfo": For footer sections

Combine these ARIA roles with semantic HTML elements like <header>, <nav>, <main>, and <footer> to create a clear structure.

For dynamic updates, use aria-live regions to notify users of changes. Adjust the priority based on the importance of the update:

aria-live="polite": For non-urgent updates
aria-live="assertive": For critical alerts
aria-atomic="true": Announces the entire region when updated

With these steps in place, you’ll create a navigation experience that’s accessible to everyone. Up next, we’ll cover guidelines for forms and interactive elements.

Form and Interactive Element Standards

Forms and interactive elements play a key role in ensuring accessibility for all users.

Form Field Labels

Labels help users understand what information is needed and how to provide it.

Use the HTML <label> element and connect it to form fields using matching for and id attributes.
Position labels above or to the left of form fields - avoid placing them inside fields as placeholder text.
Write clear, descriptive labels that specify what information is required.
Include format details directly in the label (e.g., "Phone number (###-###-####)").

Make required fields obvious both visually and programmatically:

<label for="email">
  Email address
  <span class="required" aria-label="required">*</span>
</label>
<input type="email" id="email" required>

When users provide incorrect input, display error messages clearly and effectively.

Error Message Standards

Error messages should be easy to notice and understand:

Use high-contrast colors for errors, not just red.
Place error messages close to the problematic field.
Combine text with icons to highlight errors.
Offer specific guidance on how to correct the issue.

Here's an example of a well-structured error message:

<div role="alert" class="error-message">
  <span class="error-icon" aria-hidden="true">⚠️</span>
  <p>Please enter a valid email address (example@domain.com)</p>
</div>

Finally, ensure all interactive elements work seamlessly with keyboards.

Keyboard-Ready Controls

Interactive elements should be fully operable using a keyboard:

Allow buttons and controls to be activated with the Enter or Space keys.
Use a high-contrast, visible focus indicator.
Set a logical tab order that matches the visual layout.
Add keyboard shortcuts for common actions using accesskey attributes.

For more complex elements like sliders or date pickers, provide keyboard-friendly alternatives:

<div role="slider" 
     aria-valuemin="0" 
     aria-valuemax="100" 
     aria-valuenow="50"
     tabindex="0">
  <span class="sr-only">Use arrow keys to adjust value</span>
</div>

Testing and Maintenance Steps

Once you've built accessibility into your website's content and interactive features, regular testing and upkeep are essential to maintain these standards.

Automated Test Tools

Here are some tools to help you get started:

WAVE (Web Accessibility Evaluation Tool): Identifies issues like missing alt text, poor contrast, and ARIA attribute problems.
axe DevTools: Adds accessibility testing directly into your development workflow with browser extensions.
Lighthouse: Provides detailed accessibility, performance, and best practice reports through Chrome DevTools.

Schedule these tools to run regular scans. Focus on:

Color contrast ratios
Proper heading structure
Form labels and associations
ARIA attribute usage
Keyboard navigation functionality

The insights from these scans will guide your manual testing efforts.

Manual Testing Methods

For a hands-on approach, check all interactive elements using only a keyboard. Confirm that focus indicators are clear, navigation follows a logical order, and all controls work with standard keyboard commands.

Screen Reader Testing:

Ensure content is easy to understand.
Confirm images have accurate descriptions.
Verify form fields include clear instructions.
Check that error messages are announced.
Test if dynamic content updates are accessible.

Visual Inspection:

Test text readability at zoom levels up to 200%.
Check how the layout adjusts.
Ensure content stays aligned.
Confirm interactive elements work as intended.
