A website accessibility checklist empowers you to create a more inclusive web.

1. Keyboard Navigation

Keyboard navigation is a cornerstone of website accessibility, ensuring that users who cannot use a mouse can fully interact with your website. This is crucial for people with motor disabilities, visual impairments, and even those who simply prefer the efficiency of keyboard shortcuts. Making your website keyboard navigable isn't just about compliance; it significantly improves usability for a wider audience and often simplifies the development of other assistive technology interfaces. This is why it's a critical item on any website accessibility checklist.

A keyboard-accessible website allows users to navigate through all interactive elements and functionalities using only the Tab key, arrow keys, Enter key, and Spacebar. This includes links, buttons, form fields, menus, and other interactive components.

How it Works:

Keyboard navigation relies on the browser's focus management. When you press the Tab key, the focus moves sequentially through all focusable elements on the page. Visual focus indicators highlight the currently selected element, making it clear to the user where they are on the page. Users then interact with the focused element using the Enter or Spacebar keys.

Features of Effective Keyboard Navigation:

• Clear Focus Indicators: Visible outlines or other visual cues that clearly show the currently focused element. These should be at least as prominent as :hover styles.
• Logical Tab Order: The order in which elements receive focus should follow a logical, visual flow, typically from top to bottom and left to right.
• No Keyboard Traps: Users should always be able to navigate away from an element using the keyboard.
• Access to All Interactive Elements: Every interactive element, including custom widgets, must be reachable and operable via the keyboard.

Pros:

• Improved Usability for People with Disabilities: Essential for users with motor impairments who cannot use a mouse.
• Enhanced Efficiency for Power Users: Allows experienced users to navigate and interact with your website quickly using keyboard shortcuts.
• Simplified Assistive Technology Integration: Often makes it easier for screen readers and other assistive technologies to interact with your website.

Cons:

• Thorough Testing Required: Requires careful testing across different browsers and operating systems to ensure consistent functionality.
• Complex Implementation for Interactive Applications: Implementing keyboard navigation in highly dynamic and interactive applications can be challenging.

Examples of Successful Implementation:

• GitHub: GitHub's interface is highly navigable via keyboard, allowing users to perform complex actions using shortcuts.
• Google Docs: Provides comprehensive keyboard support for document editing, formatting, and navigation.
• Twitter: Enables keyboard navigation through tweets, replies, and other actions.

Actionable Tips:

• Test with the Tab Key: Regularly test your website using only the Tab key to ensure all interactive elements are accessible and the tab order is logical. Learn more about Keyboard Navigation for best practices.
• Use CSS :focus Styles: Implement distinct :focus styles in your CSS. These should be at least as visible as :hover states.
• Implement Skip Navigation Links: Include "Skip to Main Content" links at the top of your pages to allow keyboard users to bypass repetitive navigation elements.
• Use tabindex="0": Use tabindex="0" judiciously to include custom, non-focusable elements in the tab order. Avoid positive tabindex values as they disrupt the natural flow.

By prioritizing keyboard navigation, you create a more inclusive and user-friendly experience for everyone, aligning your website with best practices for website accessibility checklists and benefiting your entire user base.

2. Alternative Text for Images

Ensuring your website is accessible to everyone, including users with visual impairments, is crucial for both ethical and practical reasons. One of the most fundamental aspects of web accessibility is providing alternative text (alt text) for images. Alt text offers a textual description of an image's content and function, allowing screen readers to convey the information to visually impaired users. It also serves as a placeholder if an image fails to load, ensuring users still understand the context. This makes alt text a critical component of any website accessibility checklist.

Alt text should be concise yet descriptive, focusing on the image's purpose and context within the page. For instance, an image of a product might have alt text like "Red leather handbag with gold clasp," while an image illustrating a concept might have alt text like "Graph showing increasing website traffic over time." This context-specific approach ensures the alt text accurately conveys the image's meaning. Features of effective alt text include concise descriptions, contextually relevant wording, empty alt attributes (alt="") for purely decorative images, and longer descriptions for complex images like charts and graphs.

Examples of Successful Implementation:

• Wikipedia: Known for its meticulous image descriptions, providing rich context and information for visually impaired users.
• The New York Times: Uses detailed and informative alt text for news images, ensuring accessibility for all readers.
• WebAIM: Their website serves as a practical demonstration of proper alt text implementation, offering valuable learning resources.

Pros of Using Alt Text:

• Essential for Screen Reader Users: Allows visually impaired users to understand and engage with visual content.
• Improved SEO: Helps search engines understand image content, contributing to better search rankings for relevant keywords like "website accessibility checklist."
• Context When Images Fail to Load: Provides a textual alternative if an image doesn't display correctly.

Cons of Implementing Alt Text:

• Requires Careful Consideration: Crafting effective alt text requires practice and thoughtfulness.
• Potential for Oversight: Alt text fields can be overlooked in some content management systems.
• Complexity for Detailed Images: Writing comprehensive descriptions for complex images can be challenging.

Actionable Tips for Writing Effective Alt Text:

• Keep it Concise: Aim for under 125 characters in most cases.
• Focus on Purpose: Describe the image's function and context rather than every visual detail.
• Decorative Images: Use alt="" (empty alt attribute) for purely decorative images. Do not omit the attribute entirely.
• Functional Images: For buttons or other interactive elements, describe the action (e.g., "Submit form," "Add to cart").
• Test with Screen Readers: Ensure your descriptions make sense and provide value in context.

For freelance web designers, digital marketing agencies, startup founders, solo entrepreneurs, and UX/UI specialists, incorporating proper alt text is essential for building inclusive and accessible websites. By prioritizing alt text, you demonstrate a commitment to providing a positive user experience for everyone while also boosting your website's SEO performance. Resources like WebAIM and JAWS screen reader documentation, popularized by accessibility advocates, provide valuable guidance on implementing effective alt text strategies. Adding alt text to your website accessibility checklist is a simple yet powerful step towards creating a more inclusive online environment.

3. Semantic HTML Structure

Semantic HTML is a cornerstone of website accessibility. It involves using HTML elements for their intended purpose, reflecting the meaning of content rather than simply dictating its appearance. This approach is crucial for assistive technologies like screen readers, which rely on semantic cues to understand the structure and hierarchy of a web page and convey that information effectively to users. A semantically structured website isn't just accessible; it's also better for SEO, maintainability, and cross-platform consistency.

Imagine a screen reader user navigating a website. Without semantic HTML, the screen reader might simply read out a string of text, making it difficult for the user to understand the page's organization. With semantic HTML, the screen reader can identify headings, navigation links, lists, and other structural elements, providing context and enabling users to navigate efficiently. This is why semantic HTML earns its place in any serious website accessibility checklist.

Key Features of Semantic HTML:

• Appropriate heading structure (h1-h6): Headings should reflect the hierarchical structure of the content, with a single <h1> for the main title and subsequent headings used to denote subsections.
• Semantic elements: Utilize elements like <nav>, <main>, <aside>, <article>, <section>, and <footer> to define different parts of the page.
• Lists: Properly mark up lists using <ul>, <ol>, and <li>.
• Tables: Use appropriate table markup with table headers (<th>) and scope attributes to define row and column headers.

Pros:

• Improved screen reader navigation and comprehension: Allows assistive technologies to interpret and convey page structure effectively.
• Enhanced SEO: Search engines utilize semantic HTML to understand content, improving search rankings.
• Increased code maintainability and understandability: Well-structured code is easier to read, update, and debug.
• Consistent structure across devices and platforms: Semantic HTML ensures that content is rendered consistently across different browsers and devices.

Cons:

It was popularized by the HTML5 specification and strongly advocated for by accessibility experts like Steve Faulkner.

4. Color Contrast and Text Readability

Color contrast and text readability are crucial aspects of website accessibility. Sufficient contrast between text and its background ensures that users with low vision, color blindness, or those using devices in bright environments can easily read the content. This is one of the most common accessibility issues found on websites, and addressing it significantly improves the user experience for everyone. Ignoring color contrast can effectively lock out a segment of your audience from accessing your website's information and services. This is why it's a vital component of any comprehensive website accessibility checklist.

This principle involves ensuring a minimum contrast ratio between the foreground (text and UI elements) and the background. For regular text, the Web Content Accessibility Guidelines (WCAG) recommend a minimum contrast ratio of 4.5:1. Larger text (18pt or 14pt bold) requires a minimum ratio of 3:1. It’s important to consider both body text and important UI components like buttons, form fields, and icons. Furthermore, your website should support text resizing up to 200% without loss of content or functionality. This allows users to adjust the text size to their preferred level of readability.

Pros:
