🔥 Ultimate CSS

The Ultimate CSS extension helps you write cleaner, more efficient styles by identifying:

• ❌ Duplicate class definitions — Flags class names that are defined multiple times across your stylesheets.
• ⚠️ Unused CSS classes — Warns you about CSS classes that are defined but not used anywhere.
• ⚠️ Undefined class usage — Highlights any class used in your HTML/JS/JSX/TS/TSX files that isn’t defined in your CSS.

⚠️ Note: SCSS support is coming soon! This version focuses on stable and accurate diagnostics for standard CSS files.

⚙️ Settings

Customize how Ultimate CSS analyzes your project by toggling a few helpful settings in the VSCode Settings UI:

• ✅ Analyze templates (HTML/JS/TS/JSX/TSX) – Detects undefined classes in your markup files
• ✅ Analyze duplicate CSS classes – Flags class names that are defined multiple times across stylesheets
• ✅ Analyze unused CSS classes – Warns you about styles that are defined but not used anywhere

You’ll find these options under “Ultimate CSS” in your VSCode Settings panel.
