PostCSS Percentage

PostCSS plugin to support percentage() function.

This plugin will transform all percentage(expression) functions to correct percentage. It's almost the same as sass function percentage, except for the support for the unit (percentage(50px / 50px)).

Installation

npm i --save postcss-percentage

Usage

postcss([ require('postcss-percentage')(opts) ])

If the input is

.box {
    width: percentage(1 / 24);
    margin: percentage(- 1 / 24) percentage(0.01 * 5);
}

Then you will get

.box {
    width: 4.166667%;
    margin: -4.166667% 5%;
}

See PostCSS docs for examples for your environment.

Options

require('postcss-percentage')({
    precision: 9,
    trimTrailingZero: true,
    floor: true
})

precision (default: 6)

Allow you to definine the precision for decimal numbers.

Note: allowed value for precision is between [0, 20].

trimTrailingZero (default: true)

Allow you to trim trailing zeroes.

When computed value is 1.234000%, we will get 1.234% instead.

floor (default: false)

Allow you to ensure the percentage will not greater than the original value. It will be quite useful to ensure the total value won't be greater than 100% (sum of some percentages).

For example, when floor is true and precision is 3, the percentage(1/24) will get 4.166% rather than 4.167%.
