While the technicalities of WCAG may take time, the benefits of providing disabled access are worth it. The following checklist, based on the WCAG 2.0 AA standard, addresses common accessibility issues:

Images

Images play a crucial role in websites, enhancing content and user experience. Ensuring accessibility for everyone is critical. Information conveyed through images, such as pictures, illustrations, or charts, must have a textual equivalent for visually impaired users relying on screen readers to understand the content. Additionally, functional alternative text provides an equivalent web experience for users with low bandwidth who disable images in their browsers.

Tips to improve images:

  • If a picture is just for looks and doesn’t tell anything important, use no text (alt=””) to avoid saying the same thing.
  • Write alt text that fits what each picture is about.
  • Include words in the alt text if a logo or image has words.
  • For pictures that do something, like buttons, use alt text that explains what it does
  • (e.g., alt=” home page”).
  • Keep alt text short for quick ID, and if needed, explain more details in a data table or elsewhere.

Contrast Ratio (Luminance Contrast)

Ensuring readability for all users, including those with color vision deficiencies, is critical to design and development. Achieving good luminance or color contrast involves creating sufficient differentiation between text and background, ensuring clear text visibility.

Tips to improve contrast ratio:

  • Follow the WCAG 2.0 AA standard, requiring a minimum contrast ratio of 4.5:1 for regular text.
  • For large-scale text and images of large-scale text (excluding logos and ‘incidental’ text), maintain a minimum contrast ratio of 3:1.
  • Pay special attention to the text within logos, ensuring it meets applicable contrast standards for clarity.

Keyboard Navigation and Visual Focus

Ensuring web accessibility for users with visual or mobility impairments is crucial, especially for those who rely on keyboards and assistive technologies.

Tips to improve keyboard navigation:

  • Make web pages, forms, media controls, and links navigable using standard keyboard commands such as “Tab,” “Shift+Tab,” “arrow keys,” and “Enter.”
  • Ensure the keyboard focus is visible, using borders or highlights as users navigate different elements.
  • Maintain a logical tab order, allowing users to navigate through content sequentially following a natural reading order.

Forms, Labels, and Errors

To ensure accessibility, forms on your website, including text fields, radio buttons, checkboxes, and drop-down lists, should feature clear and visible labels. These labels, which provide explanations about the information to be entered, must be positioned directly adjacent to the corresponding text fields. This design allows individuals with disabilities to interact with the forms seamlessly, utilizing tools like keyboards, voice input, or screen readers.

Tips for Accessible Forms:

  • Make sure form labels are accessible via the keyboard, ensuring users can efficiently navigate them.
  • Arrange form labels logically, aiding users in understanding and completing the form seamlessly.
  • It indicates required fields, avoiding sole reliance on color, and provides instructions for formats, like dates (e.g., year-month-date).
  • Ensure errors are easily noticeable, accompanied by precise guidance for users to identify and rectify the issues promptly.

Multimedia (video, audio) alternatives

Performing specific checks for video and audio is vital to accommodate blind users, those with low vision, and individuals who are deaf or hard of hearing. This involves offering alternative formats like captions or audio and text transcripts.

Tips to improve multimedia:

  • Avoid automatic start for audio or video; if necessary, include controls to pause, stop, or adjust the volume, ensuring it stops after three seconds.
  • Provide captions or “closed captions” in the relevant language, synchronized with the spoken content.
  • Include an audio description to convey essential visual information in a video.
  • Transcripts, offering a detailed account of meaningful visual content, should be easily accessible near the audio or video elements.

By incorporating these practices, websites can ensure a more inclusive experience for disabled users.

PageTitle

Page titles are displayed in the title bar or tabs of browsers and serve a crucial role in helping screen readers. These titles must be clear yet descriptive to facilitate interpretation for users with visual impairments. They play a vital role in assisting blind users to identify the current page and navigate between opened pages, as screen readers announce page titles when users transition to different web pages.

Tips to improve page title:

  • Utilize a screen reader to review your pages, ensuring each title effectively and succinctly communicates the content.
  • Inspect all website pages, guaranteeing that each title maintains sufficient distinctiveness.
  • Optimize your page titles by prioritizing essential and distinctive identifying information at the forefront. For instance, adopt a format like “Contact Us – WhoisAccessible.com” for enhanced clarity in navigation and understanding.

Link Information

Ensure your links are meaningful and easily identified by users. Descriptive link text is crucial, as it conveys the purpose and destination of the link. Avoid generic terms like “Click here” or “Read more,” as these lack distinction and prove unhelpful, especially for users relying on screen readers who often navigate through a list of links.

Tips to improve link information:

  • Ensure links are underlined when users navigate via keyboard, stylus, or voice input. This assists non-mouse users, including those with low vision or color blindness, in distinguishing links from surrounding text, promoting accessibility testing tool utilization for verification.
  • Maintain a 3:1 contrast ratio between your links and the adjacent non-link text. This practice enhances visibility and ensures accessibility, aligning with the standards validated by accessibility testing tools.
  • Specify the document type and file size When linking to files like documents or videos. This proactive approach facilitates understanding and aids users with accessibility testing tools, validating the inclusivity of this information.
  • Inform users if a link opens a new tab or file, allowing them to make an informed choice about navigating to a different destination. Incorporate accessibility testing tools to confirm compliance with standards that enhance user experience.

Headings and Landmark

Structuring content with visual headings and bulleted lists is a common practice, aiding users in navigation. To enhance accessibility for disabled users relying on keyboards and screen readers, it’s crucial to mark up headings. This ensures a comprehensible web page structure, facilitating easy navigation. Employing an accessibility testing tool during development ensures adherence to standards and enhances overall readability and user experience.

Tips to improve heading and landmark

  • Incorporate a clear and descriptive heading on every page to provide structure and assist users in understanding the content.
  • When organizing headings, prioritize a logical hierarchy (e.g., h1 to h6) to aid assistive technology users and enhance overall accessibility. Starting with an “h1” sets an ideal foundation.
  • Conceptual section headings resembling traditional headings should be marked accordingly. Employing an accessibility testing tool throughout development ensures alignment with accessibility standards, fostering readability for all users.

Appearance of Content

This aspect concerns the visual presentation of web content, encompassing factors like font changes, text size, page zoom, and line spacing, as initiated by web users. Users relying on screen-zoom software may enlarge content for readability. Therefore, it’s crucial for web content to maintain readability and proper structure, preventing usability issues caused by overlapping. Consistent adherence to accessibility standards, verified through an accessibility testing tool, contributes to an inclusive online experience.

Tips to improve the appearance of content:

  • When enlarging a web page’s text size, verify that text remains visible without disappearing or getting cut off.
  • Present text in actual format, avoiding using the images to ensure accessibility.
  • Prevent overlaps between web content, including text and images.
  • Ensure visibility and usability of controls like buttons and form fields.
