Step 1: CSS Audit and Analysis Checklist

Identify all CSS files and their locations

• Run the CSS audit script to find all CSS files
• Document file paths, sizes, and last modified dates
• Categorize files by purpose (global, component-specific, vendor, etc.)

Document current organization pattern (if any)

• Analyze folder structure
• Identify naming conventions
• Document import/include patterns
• Note any CSS methodology currently in use

Identify duplicate styles and redundancies

• Check for repeated color values
• Look for duplicate media queries
• Find repeated selector patterns
• Identify redundant property declarations

Note browser compatibility issues

• Check for vendor prefixes
• Identify CSS features with limited browser support
• Document any browser-specific hacks or workarounds

Screenshot key UI components for reference

• Navigation elements
• Buttons and CTAs
• Form elements
• Cards and containers
• Typography examples
• Icons and decorative elements
• Modals and overlays
• Tables and data displays

Document current styling patterns

• Color usage patterns
• Spacing and layout patterns

Check for overly specific selectors

• Calculate specificity scores
• Identify selectors with unnecessary specificity
• Note excessive nesting

Identify render-blocking CSS

• Check how CSS is loaded (inline, external, etc.)
• Identify critical vs. non-critical CSS
• Measure CSS loading performance

Look for unused CSS

• Run coverage analysis in browser dev tools
