ARIA-describedby example

Description:聽The WAI-ARIA ‘aria-describedby’ attribute has a reference to an ID that does not exist or an ID that is not unique.

Context:聽All ARIA tags must reference elements that exist on the page, an ID should only be used once on any given page.

<table class="table table-responsive" aria-describedby="summary">
   <caption>
     糖心视频 M膩noa Materials Deadlines
   </caption>
</table>

How to fix it:聽Use semantic elements to indicate emphasis or structure, and CSS to handle styling.

<table class="table table-responsive" aria-describedby="summary">
   <caption>
     糖心视频 M膩noa Materials Deadlines
   </caption>
</table>
<p id="summary">A table of material deadlines for 糖心视频 M膩noa</p>
