A recent refresh of Section 508 in 2018 called for government websites to meet the guidelines of the WCAG 2.0 and create content focused on four principles:

  • Perceivable – It must be presented in a way that can be easily perceived.

1.1Text AlternativesMake sure all images and non-text content have descriptions so that people who use screen readers or other assistive technology can understand them. This includes providing descriptions for ensuring image accessibility and transcripts for audio content.
1.2Time-based MediaAdd captions or descriptions to videos and audio recordings, so people who are deaf or hard of hearing can follow along. Also, provide alternative formats for those who may have trouble accessing the content in its original format. Following this guideline is important to ensure audio and video accessibility.
1.3AdaptableCreate content that can adjust to different formats without losing its meaning or structure. This makes it easier for users to access the content on various devices and platforms according to their preferences.
1.4DistinguishableImprove content visibility by ensuring clear contrast between foreground and background elements. This helps users with visual impairments better distinguish between different parts of the content.


  • Operable – It must be easy to navigate for all users, including those who rely on assistive technology.

2.1Keyboard AccessibleEnsure all website features can be accessed and operated using only the keyboard, without needing specific timings for keystrokes. This is important for users who navigate websites without a mouse, like those with motor disabilities.
2.2Enough TimeGive users sufficient time to read and understand website content. Avoid automatic page refreshes or redirects that might disrupt users. Also, ensure interactive elements don’t time out too quickly, allowing users to complete tasks comfortably.
2.3SeizuresDesign website content to avoid flashing elements that could trigger seizures in users with photosensitive epilepsy. Limit flashing to no more than three times per second to reduce the risk of adverse reactions. This helps create a safer browsing environment for all users.
2.4NavigableMake it easy for users to move around the website by providing clear navigation menus, breadcrumbs, and page structures. Help users understand where they are on the site and how to find what they’re looking for. Ensure interactive elements are clearly labeled and structured for easy comprehension.
2.5Input Modalities (WCAG 2.1 & WCAG 2.2)Support various input methods beyond keyboards, such as touchscreens or voice commands, to enhance accessibility. This accommodates users with different abilities and preferences, making the website more inclusive and user-friendly.


  • Understandable – People of all disabilities must understand it.

3.1ReadableMake sure website content is easy to read and understand by using clear and simple language. This helps users grasp information without difficulty.
3.2PredictableDesign website content and layouts in a consistent and easy-to-follow manner, so users can navigate and interact with confidence. Consistent design helps users know what to expect, reducing confusion.
3.3Input AssistanceHelp users provide accurate information and avoid mistakes by giving clear instructions and implementing error prevention techniques. Provide helpful cues and feedback during form submissions to guide users and prevent errors.
3.3Input AssistanceHelp users provide accurate information and avoid mistakes by giving clear instructions and implementing error prevention techniques. Provide helpful cues and feedback during form submissions to guide users and prevent errors.


  • Robust – It should be accessible and adjustable to keep up with improving technology.
