 Differences:

 1. `clientWidth` is numeric, while `getComputedStyle(elem).width` returns a string with `px` at the end.
 2. `getComputedStyle` may return non-numeric width like `"auto"` for an inline element.
 2. `getComputedStyle` may returnanon-numeric width like `"auto"` for an inline element.
 3. `clientWidth` is the inner content area of the element plus paddings, while CSS width (with standard `box-sizing`) is the inner content area *without paddings*.
 4. If there's a scrollbar and the browser reserves the space for it, somebrowser substract that space from CSS width (cause it's not available for contentany more), and some do not. The `clientWidth` property is always the same: scrollbar size issubstracted if reserved.
 4. If there's a scrollbar and the browser reserves the space for it, somebrowsers subtract that space from CSS width (because it's not available for contentanymore), and some do not. The `clientWidth` property is always the same: scrollbar size issubtracted if reserved.
