# [postcss][postcss]-reduce-idents [][ci] [][npm] [][deps]
|
|
|
|
> Reduce [custom identifiers][idents] with PostCSS.
|
|
|
|
## Install
|
|
|
|
With [npm](https://npmjs.org/package/postcss-reduce-idents) do:
|
|
|
|
```
|
|
npm install postcss-reduce-idents --save
|
|
```
|
|
|
|
## Example
|
|
|
|
### Input
|
|
|
|
This module will rename custom identifiers in your CSS files; it does so by
|
|
converting each name to a index, which is then encoded into a legal identifier.
|
|
A legal custom identifier in CSS is case sensitive and must start with a
|
|
letter, but can contain digits, hyphens and underscores. There are over 3,000
|
|
possible two character identifiers, and 51 possible single character identifiers
|
|
that will be generated.
|
|
|
|
```css
|
|
@keyframes whiteToBlack {
|
|
0% {
|
|
color: #fff
|
|
}
|
|
to {
|
|
color: #000
|
|
}
|
|
}
|
|
|
|
.one {
|
|
animation-name: whiteToBlack
|
|
}
|
|
```
|
|
|
|
### Output
|
|
|
|
```css
|
|
@keyframes a {
|
|
0% {
|
|
color: #fff
|
|
}
|
|
to {
|
|
color: #000
|
|
}
|
|
}
|
|
|
|
.one {
|
|
animation-name: a
|
|
}
|
|
```
|
|
|
|
Note that this module does not handle identifiers that are not linked together.
|
|
The following example will not be transformed in any way:
|
|
|
|
```css
|
|
@keyframes fadeOut {
|
|
0% { opacity: 1 }
|
|
to { opacity: 0 }
|
|
}
|
|
|
|
.fadeIn {
|
|
animation-name: fadeIn;
|
|
}
|
|
```
|
|
|
|
It works for `@keyframes`, `@counter-style` and custom `counter` values. See the
|
|
[documentation][idents] for more information, or the [tests](test.js) for more
|
|
examples.
|
|
|
|
## Usage
|
|
|
|
See the [PostCSS documentation](https://github.com/postcss/postcss#usage) for
|
|
examples for your environment.
