@ShuraimHassan said in is custom.css only for default modules?:

could you show me an Example that how Can I do this?

do what? make a module, add a css style to an element?

I don’t know ‘responsive’. currently main.css is in pixels for 1920x1080.

I have a version I converted to vh/vw.

3rd party. mm supplies font_awesome.
(see the fonts folder)
other than that every module can use whatever they want. no restrictions.
