Common CSS Formatting Issues
Unreadable Minified CSS
Large blocks of CSS with no line breaks or indentation are hard to work with. Formatting makes these readable again.
Inconsistent Indentation
Mixed spaces and tabs create confusion. Our formatter standardizes indentation for consistency.
Messy Property Organization
Randomly ordered properties make CSS hard to navigate. Formatting organizes them logically.
Missing Whitespace
Lack of spacing around selectors and properties makes code dense and hard to read.
Use Cases for CSS Formatting & Minifying

Format CSS during development for better readability and easier debugging.
Production Optimization
Minify CSS before deployment to reduce file size and improve loading speed.
Code Reviews
Format CSS before code reviews to ensure consistency and readability.
