Implement hybrid CSS architecture to fix white-on-white modal issue on sites with CSS resets
- Migrate from inline CSS to external insertr.css with cascade layer architecture
- Add CSS CDN serving capability (ServeInsertrCSS handler and /insertr.css route)
- Implement hybrid approach: @layer insertr for modern browsers + html body selectors for legacy browsers
- Remove scattered inline CSS from JavaScript modules for better maintainability
- Solve form element spacing conflicts with aggressive site CSS resets like '* {margin:0; padding:0}'
- Enable proper CSS caching and separation of concerns

HYBRID CSS ARCHITECTURE:
|
||||
|
||||
This CSS uses a hybrid approach for maximum browser compatibility:
|
||||
|
||||
1. MODERN BROWSERS: @layer insertr provides cascade layer isolation
|
||||
- Layered styles automatically win over unlayered styles
|
||||
- Clean separation regardless of specificity
|
||||
- Future-proof CSS architecture
|
||||
|
||||
2. LEGACY BROWSERS: Higher specificity fallback selectors
|
||||
- html body .insertr-* selectors (0,0,3,0) beat universal * (0,0,0,1)
|
||||
- Works in all browsers back to IE6
|
||||
- Ensures consistent behavior across environments
|
||||
|
||||
This ensures our form elements maintain proper spacing and styling
|
||||
even on sites with aggressive CSS resets like "* {margin:0; padding:0}"
