In the previous post (closed) they explained to me how to modify the transparency of the modules, but only applied at the beginning ... Well, how can I do the same with other existing modules ?, for example JA Masthead
Hi delinea
Since each module is using a specific div class would be better to have a look at each module you want to modify and then add the specific class in custom.css file, there is no single class to modify opacity that can be valid for all modules.
Example for masthead
.ja-masthead .ja-masthead-detail { opacity:0.5; }
Change value as you wish
Hope it helps
