### Why is this important?
The CSS `::before` and `::after` pseudo-elements specify the location of content to be inserted before and after an element's document tree content.
For users who need to customize or turn off style information to view content according to their needs,
assistive technologies might not be able to access the information that is inserted using CSS.
<!-- This is where the code snippet is injected -->
<div id="locSnippet"></div>
### What to do
* Verify that any content inserted by the CSS `::before` and `::after` pseudo-elements are purely decorative
* **Or**, disable CSS styles and verify that non-decorative information in the inserted content is still available
* **Or**, include the important information directly in the page
