CSS Tidier is a JavaScript implementation of reindenter and reformatter for CSS stylesheets.

Given the following style:

menu{color:red} navigation{background-color:#333}

CSS Tidier will produce:

menu {
    color: red
}

navigation {
    background-color: #333
}

Try it online at github css-tidier. For the command-line use, install Node.js css-tidier package.

For more examples, see also its test suite.

Since CSS Tidier is written in pure JavaScript, it can run anywhere that JavaScript can run.

The API is very simple:

var result = css-tidier(style, options);

options is an optional object to adjust the formatting. Known options so far are:

• autosemicolon always inserts a semicolon after the last ruleset (default is 'false')
• braceonnextline defines the placement of open curly brace.
• indent is a string used for the indentation of the declaration (default is 2 spaces)

Example call:

var tidied = css-tidier('menu{opacity:.7}', {
    indent: '  ',
    openbrace: 'separate-line',
    autosemicolon: true
});

npm install -g css-tidier
css-tidier style.css # tidied CSS is output to console
css-tidier style.css >style.tidied.css # write to file
curl http://example.com/style.css | css-tidier # tidy from stdin
