Usage

Add PostCSS Attribute Case Insensitive to your project:

npm install postcss postcss-attribute-case-insensitive --save-dev

Use it as a PostCSS plugin:

const postcss = require('postcss');
const postcssAttributeCaseInsensitive = require('postcss-attribute-case-insensitive');

postcss([
	postcssAttributeCaseInsensitive(/* pluginOptions */)
]).process(YOUR_CSS /*, processOptions */);

Options

preserve

The preserve option determines whether the original notation is preserved. By default, it is not preserved.

postcssAttributeCaseInsensitive({ preserve: true })
