dom-css

Small module for fast and reliable DOM styling.

• detects prefixes as necessary, cached for performance
• converts numbers to px strings for common properties
• normalizes for camel and dash case

var css = require('dom-css')

//set a style
css(element, 'position', 'absolute')

//will be set as "WebkitFontSmoothing" on Chrome
css(element, 'font-smoothing', 'none')

//set multiple styles
css(element, {
    //can be camel or dash case
    'background-color': 'blue',

    //some properties use 'px' by default
    left: 25, 
    top: 0,
    marginTop: 0,
    position: 'absolute'
})

//get the current style
css.get(element, 'position') 
// -> 'absolute'

css.get(element, ['left', 'marginTop']) 
// -> { left: '25px', marginTop: '0px' }

See the special cases for a list of px-suffixed properties (same list is used in GreenSock API).

Usage

css(element, property, value)

css.set(element, property, value)

Styles an element with the css property (dash or camel case) and a given value. value is a string, or a number to be suffixed with 'px' (special cases, see below).

css(element, styles)

css.set(element, styles)

A shorthand for setting multiple styles, where styles is an object containing property:value pairs.

css.get(element, prop)

Gets the inline style of element, where prop is a string (like "borderRadius") or an array of strings. If an array of strings is given, an object is returned with key-value pairs representing the specified properties.

css.get(div, ['width', 'height']) => { width: "20px", height: "40px" }

Note: This does not provide the computed style!

top, right, bottom, left, 
width, height, fontSize,
