🔍 6. What Was Causing the Error

Primary Issue: CSS Syntax Error

Saat menambahkan responsive CSS rules, terjadi kesalahan dalam struktur penulisan yang menyebabkan:

Extra closing brace: Kurung kurawal penutup berlebih
Broken nesting: Struktur CSS yang tidak lengkap
Orphaned selectors: Selector yang tidak memiliki parent yang tepat

Secondary Issue: Browser Compatibility

backdrop-filter property memerlukan vendor prefix untuk Safari:

Safari 9+: Memerlukan -webkit-backdrop-filter
Modern browsers: Mendukung backdrop-filter standar
