Problems Accessibility with 1.3.1 WCAG

[jahernae]

Hi!
We are currently validating the accessibility of our website using various tools, and we've encountered an issue related to WCAG 2.2 guideline 1.3.1. The problem seems to be caused by the use of :after or :before pseudo-elements in the CSS.

According to accessibility best practices, it's generally not recommended to generate content purely via CSS. However, we've found the following example in cookieconsent.css:

.pm__table-td:before {
  color: var(--cc-primary-color);
  content: attr(data-column);
....
}

Do you have any suggestions or solutions regarding this?
Thanks a lot in advance!
