|
|
[](https://travis-ci.org/MoOx/reduce-css-calc)
|
|
|
|
> Reduce CSS calc() function to the maximum.
|
|
|
|
Particularly useful for packages like [rework-calc](https://github.com/reworkcss/rework-calc) or [postcss-calc](https://github.com/postcss/postcss-calc).
|
|
|
|
## Installation
|
|
|
|
```console
|
|
npm install reduce-css-calc
|
|
```
|
|
|
|
## Usage
|
|
|
|
### `var reducedString = reduceCSSCalc(string, precision)`
|
|
|
|
```javascript
|
|
var reduceCSSCalc = require('reduce-css-calc')
|
|
|
|
reduceCSSCalc("calc(1 + 1)")
|
|
// 2
|
|
|
|
reduceCSSCalc("calc((6 / 2) - (4 * 2) + 1)")
|
|
// -4
|
|
|
|
reduceCSSCalc("calc(1/3)")
|
|
// 0.33333
|
|
|
|
reduceCSSCalc("calc(1/3)", 10)
|
|
// 0.3333333333
|
|
|
|
reduceCSSCalc("calc(3rem * 2 - 1rem)")
|
|
// 5rem
|
|
|
|
reduceCSSCalc("calc(2 * 50%)")
|
|
// 100%
|
|
|
|
reduceCSSCalc("calc(120% * 50%)")
|
|
// 60%
|
|
|
|
reduceCSSCalc("a calc(1 + 1) b calc(1 - 1) c")
|
|
// a 2 b 0 c
|
|
|
|
reduceCSSCalc("calc(calc(calc(1rem * 0.75) * 1.5) - 1rem)")
|
|
// 0.125rem
|
|
|
|
reduceCSSCalc("calc(calc(calc(1rem * 0.75) * 1.5) - 1px)")
|
|
// calc(1.125rem - 1px)
|
|
|
|
reduceCSSCalc("-moz-calc(100px / 2)")
|
|
// 50px
|
|
|
|
reduceCSSCalc("-moz-calc(50% - 2em)")
|
|
// -moz-calc(50% - 2em)
|
|
```
