Documentation

computedStyle is a single purpose function

computedStyle(element, property);
/**
 * Cross-browser getComputedStyle
 * @param {HTMLElement} el Element to get property from
 * @param {String} prop Property to look up (DOM, zIndex, and CSS, z-index, formats accepted)
 * @returns Property from the browser
 *
 * @note These properties can vary from browser to browser.
 * For example, IE6 will return #FF0000 whereas Firefox will return rgb(255, 0, 0)
 * I have chosen to avoid this for this repo as it exits the single purpose
 * and jQuery follows the same approach.
 */

Examples

// Grab the z-index of an element
computedStyle(el, 'z-index');

// Grab the background-color of an element
computedStyle(el, 'background-color');
