I thought it was announced that CSS will no longer be supported in Glide Apps soon. Or did they change that decision? (⚠️ Unsupported HTML/CSS in the Rich Text component will completely break in the coming weeks)
I do have the business plan, but I haven’t tried implementing CSS yet.
According to the documentation, Glide does support SVGs. (Glide Docs • Adding images)
File types
Glide recognizes JPGs, PNGs, GIFs, and SVGs.
For your app’s icon, it’s best to use a simple SVG. The project icon will appear in many places and many sizes so it’s best to use an SVG icon that will scale and look good at any size.
