This CSS file intends to warn developers about possible risks and mistakes that exist in HTML code. It can also be used to roughly evaluate a site’s quality by simply including it as an external stylesheet.
When activating the stylesheet, a tip should appear beside each incriminated elements, displaying what’s going on.
This file is not a replacement to a complete tool such as aXe, Tanaguru or Tenon. It only intends to show possible weaknesses. You should obviously do some manual check by hand to know whether the code should or should not be fixed.
Note: CSS best practices do not belong to this CSS file. Some selectors are ugly as hell, but we need them in order to select what we need to select.
