PostCSS Nesting Experimental 
PostCSS Nesting Experimental lets you nest style rules inside each other, following the CSS Nesting specification. If you want nested rules the same way Sass works you might want to use PostCSS Nested instead.
[!WARNING] Experimental version of PostCSS Nesting
1a, b { 2 color: red; 3 4 & c, & d { 5 color: white; 6 } 7 8 :is(e) & { 9 color: yellow; 10 } 11} 12 13& { 14 color: pink; 15} 16 17 18/* becomes */ 19 20a, b { 21 color: red; 22} 23 24:is(a,b) c, :is(a,b) d { 25 color: white; 26 } 27 28:is(e) :is(a,b) { 29 color: yellow; 30 } 31 32:scope { 33 color: pink; 34}
Relative selectors :
1.parent { 2 color: red; 3 4 .child { 5 color: white; 6 } 7 8 > .other-child { 9 color: yellow; 10 } 11} 12 13/* becomes */ 14 15.parent { 16 color: red; 17} 18 19:is(.parent) .child { 20 color: white; 21} 22 23:is(.parent)> .other-child { 24 color: yellow; 25}
Usage
Add PostCSS Nesting Experimental to your project:
1npm install @csstools/postcss-nesting-experimental --save-dev
Use PostCSS Nesting Experimental as a PostCSS plugin:
1import postcss from 'postcss'; 2import postcssNestingExperimental from '@csstools/postcss-nesting-experimental'; 3 4postcss([ 5 postcssNestingExperimental(/* pluginOptions */) 6]).process(YOUR_CSS /*, processOptions */);
PostCSS Nesting Experimental runs in all Node environments, with special instructions for:
| Node | Webpack | Gulp | Grunt |
|---|
⚠️ Spec disclaimer
The CSS Nesting specification states on nesting that "Declarations occurring after a nested rule are invalid and ignored.".
While we think it makes sense on browsers, enforcing this at the plugin level introduces several constraints that would
interfere with PostCSS' plugin nature such as with @mixin
