It stands for cascading style sheets and it lets you change colors, fonts, borders, etc. Due to the somewhat counter-intuitive nature of CSS, it can cause some serious frustration with front-end.. :nth-child(2n of ul, ol) { color: red } :nth-child(3n + 1 of img) { color: yellow } :not(div, ol, ul) { color: green } :has(:matches(ul, ol), ul, ol) { color: blue } Turns into:.module1-foo { color: red; } .module1-bar { font-size: 1.5em; background: yellow; } .module2-baz { color: red; } .module2-qux { font-size: 1.5em; background: yellow; width: 50px; } It can be assumed that first two rules are never used with the second two on the same markup. But we can't say that for sure without a markup review. The optimizer doesn't know it either and will perform safe transformations only. The result will be the same as input but with no spaces and some semicolons:

Transform CSS with the power of JavaScript. Auto-prefixing, future CSS syntaxes, modules, linting and more are possible with hundreds of PostCSS plugins All sections are optional. Value of tags, ids and classes should be an array of a string, value of scopes should be an array of arrays of strings. Other values are ignoring.
