getCSSProperty

Get a css property from a DOM-element selected by given selector. The return value is formatted to be testable. Colors gets parsed via rgb2hex and all other properties get parsed via css-value.

Note that shorthand CSS properties (e.g. background, font, border, margin, padding, list-style, outline, pause, cue) are not returned, in accordance with the DOM CSS2 specification - you should directly access the longhand properties (e.g. background-color) to access the desired values.

Usage

$(selector).getCSSProperty(cssProperty)

Parameters

Name	Type	Details
cssProperty	String	css property name

Examples

<label id="myLabel" for="input" style="color: #0088cc; font-family: helvetica, arial, freesans, clean, sans-serif, width: 100px">Some Label</label>

it('should demonstrate the getCSSProperty command', () => {
    const elem = $('#myLabel')
    const color = elem.getCSSProperty('color')
    console.log(color)
    // outputs the following:
    // {
    //     property: 'color',
    //     value: 'rgba(0, 136, 204, 1)',
    //     parsed: {
    //         hex: '#0088cc',
    //         alpha: 1,
    //         type: 'color',
    //         rgba: 'rgba(0, 136, 204, 1)'
    //     }
    // }

    const font = elem.getCSSProperty('font-family')
    console.log(font)
    // outputs the following:
    // {
    //      property: 'font-family',

    //      }
    // }

    var width = elem.getCSSProperty('width')
    console.log(width)
    // outputs the following:
    // {
    //     property: 'width',
    //     value: '100px',
    //     parsed: {
    //         type: 'number',
