rule-select

Select and apply css rules with css selectors

Usage

app.jade:

import {mount} from 'ui-kit-rule-select'
import './index.ess'

export var mixins = [mount];

index.ess:

import R from 'ui-kit-rule-select'

div
  color red

span
  color R['div']['color']

Example

In this simple example, our app has loaded the materialize css framework on the page. But instead of applying a lot of classes and rules to our markup, we can pluck out the rule values we want and assign them individually to rules and selectors that we choose.

jade:

h1 woah
h2 cool
h3 nice

.primary i'm primary colored
.accent i'm accent

ess:

import R from 'ui-kit-rule-select'

// with this function, you can use css
// rules on the page as variables

h1
  color blue

h2
  background-color = R['h1']['color']

// external scripts works just as well

h2
  border 5px solid
  border-color = R['.materialize-red']['background-color']
  color = R['.green.lighten-2']['background-color']

// you can reference rules that are
// pointing to other rules if you want

h3
  background-color = R['h2']['border-color']

// or leverage custom properties to piece together
// your custom palette

:root
  --primary = R['.orange.lighten-1']['background-color']
  --accent = R['.purple.darken-2']['background-color']

.primary
  background-color var(--primary)
.accent
  background-color var(--accent)
