Axe Core 4.8 rules tagged as critical.
A label element with a programmatic association must be included for each select element.
To make forms accessible, they must have clear form labels. Even if a form element isn’t programmatically named, sighted users can usually tell what it’s for when they see checkboxes, radio buttons, input fields, etc. To identify form fields, screen reader users need clear form labels. All form elements should have labels to remove confusion and make the product more accessible.
Screen reader users are in the dark about the expected input data when form elements lack labels. Without a defined label connection (or redundant text acting as a label), screen readers cannot automatically determine information about input items.
What this Accessibility Rule Checks
ensures that each select element has a label that is associated with it programmatically.
Markup for data tables can be tedious and perplexing. Tables must be semantically marked up and have the proper header structure. Table navigation is made easier by features in screen readers, but for these capabilities to function properly, the tables must be precisely marked up.
Tables are announced in a certain way by screen readers. The potential for unclear or erroneous screen reader output exists when tables are not properly marked up.
Screen reader users are unable to correctly understand the relationships between the cells and their contents visually when tables are not adequately structured and marked up semantically.
What this Accessibility Rule Checks
Verifies the correct header structure and semantic markup of data tables.
A track element with the property set to kind="captions" is required for an HTML5 video element. For deaf viewers, the captions must include all audible cues from the video, such as dialogue, musical cues, sound effects, and other pertinent information.
Users who are hard of hearing have limited or no access to a video’s content if it lacks a caption. Even if there is a captioning track, make sure it includes all of the video’s important content and not just the dialogue.
Without captions, deaf viewers are able to see everything in the video but are unable to hear anything. The dialogue, narration, and other crucial sounds that are not spoken by people—such as “dramatic instrumental music,” clapping, screaming, or other sounds that create the scene, provide context, or otherwise give meaning to the video—are not audible to deaf viewers without a caption track.
What this Accessibility Rule Checks
Makes sure all video elements have captions.
