How to Use CSS Formatter Online: Step-by-Step Guide
Format, indent, and organize CSS stylesheets with uniform selector rules and property spacing
About CSS Formatter — Free Online Tool
CSS Formatter expands a stylesheet so each declaration sits on its own line inside its rule.
Before anything is reformatted the braces are counted, and a sheet whose opening and closing counts disagree is refused with both totals shown — that one check usually finds the typo faster than rereading the file does. Each declaration is then reprinted on its own line with a terminating semicolon added if it was missing, nested at-rules such as @media are indented along with their contents, and quoted strings pass through untouched so a content value survives intact. Properties stay in the order you wrote them: there is no alphabetical sort.
Formatting runs in the page, so the stylesheet never leaves your device.
Reading a theme stylesheet that shipped minified, hunting the missing brace that broke a build, tidying CSS copied out of a devtools panel, and normalising a file before committing it.
