I searched for a plugin that could help me to change the visual of my hyperlinks but I didn’t find it. So I tried to do it on Microthemer… But I couldn’t find the exactly ‘code’/’destination’ for the hyperlink selector, so I could change its CSS.
The selector you’ve chosen in your first screenshot looks appropriate for styling the links. If you have tried adding styles, which aren’t working, I would need a link to the page in order to analyse what’s going on.
In general, the way to give black links a yellow underline, is to set a bottom border, or box-shadow. That way the color of the underline can differ from the text.
