Hi everyone, I'm reopening this issue as it's still occurring and affecting my character sheet development. The problem persists even when using FontAwesome icons in CSS. The Issue: When I include SVG images or FontAwesome icon references in my CSS file, the styling for roll templates gets completely broken, even though other CSS rules apply normally. Removing the SVG/icon references fixes the issue immediately. What I've Tried: - Converting Sass to plain CSS - Using different SVG formats - Implementing FontAwesome icons via CSS - Testing in the custom sheet sandbox Current Status: The error appears to be a CSS security filter on Roll20's end that's too aggressive. It seems to block entire CSS rule sets when it detects certain content (SVGs, possibly certain characters in calc() functions, or icon references), rather than just sanitizing the problematic parts. Questions: 1. Is there a known workaround for using icons/SVGs in character sheets without breaking roll templates? 2. Are there specific characters or patterns I should avoid in my CSS? 3. Has this been escalated as a bug? If so, what's the status? Any insights or workarounds would be greatly appreciated! Thanks
