Clean CSS is easy to read, easy to understand, and easy to maintain.
When projects grow, messy CSS becomes hard to fix and update.
Professional developers always write CSS that others can read and reuse.
Well formatted CSS is easier to debug and update.
Spacing, indentation, and line breaks make a big difference.
Readable CSS helps teams work together.
Good formatting reduces mistakes and saves time.
Grouping related styles makes your CSS easier to understand.
Future updates become simple and safe.
Rules for clean CSS
- Use proper spacing and indentation
- Write one property per line
- Use meaningful class names
- Group related styles together
- Remove unused code
Clear class names explain what the style is for.
