PostCSS IC Unit lets you use the ic length unit, following the CSS Values and Units Module specification.
```pcss p { text-indent: 2ic; }
.bubble { width: calc(8ic + 20px); }
/ becomes / p { text-indent: 2em; }
.bubble { width: calc(8em + 20px); } ```
See prior work by JLHwung here postcss-ic-unit To ensure long term maintenance and to provide the needed features this plugin was recreated based on JLHwung's work.
Add PostCSS IC Unit to your project:
bash
npm install postcss @csstools/postcss-ic-unit --save-dev
Use it as a PostCSS plugin:
```js const postcss = require('postcss'); const postcssIcUnit = require('@csstools/postcss-ic-unit');
postcss([ postcssIcUnit(/ pluginOptions /) ]).process(YOUR_CSS /, processOptions /); ```
PostCSS IC Unit runs in all Node environments, with special instructions for:
| Node | PostCSS CLI | Webpack | Create React App | Gulp | Grunt | | --- | --- | --- | --- | --- | --- |
The preserve option determines whether the original source
is preserved. By default, it is not preserved.
js
postcssIcUnit({ preserve: true })
```pcss p { text-indent: 2ic; }
/ becomes /
p { text-indent: 2em; text-indent: 2ic; } ```
