the css formatter this tool pretty prints css paste in a stylesheet minified or just inconsistently indented and it reformats it with consistent indentation one declaration per line and normalized spacing around colons and braces it also lowercases hex colors so ffffff becomes ffffff and normalizes quotes to double quotes inside url and font family values formatting runs entirely in your browser via prettier s standalone build the stylesheet you paste is never sent to a server under the hood this is prettier 3 s standalone build not a hand rolled regex formatter the page dynamically imports prettier standalone plus prettier plugins postcss the same postcss based plugin that also powers the less and scss formatters since prettier ships one parser package for all three the standalone build skips node s fs module which is what lets it run in the browser at all the tab size control maps directly to prettier s tabwidth option the semicolons checkbox visible on the javascript and typescript formatters doesn t appear here because css declarations always end in and prettier has no option to change that reach for this when you have css in a form you can t read comfortably output copied from a browser s computed styles panel a minified vendor stylesheet or a build artifact pasted into a bug report it also doubles as a syntax check an unclosed brace or stray token makes prettier s parser throw a csssyntaxerror naming the exact line and column instead of silently passing through broken css that s useful before a code review or before committing a stylesheet you edited by hand examples reformatting a minified stylesheet css input card background ffffff padding 10px 20px border radius 4px card title font size 18px font weight bold color 333 output tab size 2 default card background ffffff padding 10px 20px border radius 4px card title font size 18px font weight bold color 333 verified against the tool s prettier build one declaration per line consistent spacing and ffffff lowercased to ffffff named color keywords like red are left untouched only hex literals get case normalized invalid css throws it doesn t pass through silently css card color red this exact input throws syntaxerror csssyntaxerror unclosed block 1 1 instead of returning the input unchanged checked against the tool s prettier build 1 1 is the line and column of the unclosed tab size and custom properties css input root main color ff0000 gap 8px btn font family arial sans serif output tab size 4 root main color ff0000 gap 8px btn font family arial sans serif this run used tab size 4 from the toolbar default is 2 main color keeps its exact name since only values are normalized and the single quotes around arial become double quotes prettier s default for css strings frequently asked questions does this tool minify css or only format it it only formats the format button re indents and cleans up spacing but doesn t reduce file size for minification use the css beautifier and minifier which pairs the same prettier based formatting with a one click minify will formatting change how my css behaves no it only changes whitespace indentation and a couple of cosmetic details hex colors are lowercased and decimals gain a leading zero 5em becomes 0 5em never selectors or the effective value of a property is my css uploaded anywhere no formatting runs entirely in your browser through prettier s standalone build nothing you paste is sent to a server logged or stored can i format scss or less with this page it parses plain css only simple stylesheets often go through fine but scss specific syntax like variable interpolation and less mixin calls like mixin throw a syntax error here use the scss code formatter or less code formatter instead same prettier engine configured for that syntax why is there no semicolons option like on the javascript formatter css declarations always end in a semicolon inside a rule block and prettier has no option to change that the semicolons checkbox only affects the javascript and typescript formatters so it s hidden here related tools css beautifier and minifier same prettier engine for beautify plus a one click minify scss code formatter handles sass specific syntax like interpolation that this page rejects less code formatter handles less mixin calls and other syntax this page rejects hex color calculator build or convert the hex color values that show up in your css learn more lesson css syntax the declaration and rule block structure this formatter re indents lesson css media rule how the nested media blocks in the examples above are structured lesson css color property why hex keyword and functional color values format differently w3docs tutorial esempi esercizi snippet e quiz
