About CSS Formatting
What is CSS?
CSS (Cascading Style Sheets) controls the visual presentation of HTML elements — colors, layouts, fonts, spacing, animations, and responsive design. Clean, well-organized CSS is essential for maintainable web projects.
How to Format CSS Online
Paste your CSS code, click Format, and get properly indented CSS with one property per line, consistent spacing around colons and braces, and organized rule blocks. The tool also validates your CSS and detects common errors like unclosed braces and missing colons.
CSS Validation Features
The formatter catches unclosed braces, unclosed parentheses (broken gradients, calc values), missing colons in property declarations, empty values, unclosed comments, and extra closing characters. It shows the exact position of each error in the editor.
