* which work perfectly for all Shuffle's use cases.
|
|
*
|
|
* 1. getBoundingClientRect() `left` and `right` properties.
|
|
* - Accounts for transform scaled elements, making it useless for Shuffle
|
|
* elements which have shrunk.
|
|
* 2. The `offsetWidth` property.
|
|
* - This value stays the same regardless of the elements transform property,
|
|
* however, it does not return subpixel values.
|
|
* 3. getComputedStyle()
|
|
* - This works great Chrome, Firefox, Safari, but IE<=11 does not include
|
|
* padding and border when box-sizing: border-box is set, requiring a feature
|
|
* test and extra work to add the padding back for IE and other browsers which
|
|
* follow the W3C spec here.

* @param {Element} element The element.
|
|
* @param {boolean} [includeMargins] Whether to include margins. Default is false.
