How to catch all links (that are colored with link color)?

Hello,

in addition to the link color, we would like to underline all links that are only colored with the link color. Unfortunately, all <a> elements will be colored with the link color, including blog titles, wiki titles, etc. But these are overwritten by new classes. The problem now is that there is no class with which we can underline all links without selecting all <a> elements. To exclude the classes individually is inefficient and could become incosistent in the future (with new features from coyo). How to solve this? Just looking at the future (EU plans to make accessible websites mandatory) this is a highly important issue.

Best regards,
Moritz
