<pre>Demo here:
<a href="http://jsfiddle.net/sbel/sykrLf2u/6/">http://jsfiddle.net/sbel/sykrLf2u/6/</a>
Steps to reproduce the problem:
1. Create an absolutely positioned element at left: 0.
2. Get offsetWidth of element.
2. Move element to left: .1px
3. Get offsetWidth of element.
What is the expected behavior?
The offsetWidths should match.
What went wrong?
When the element is positioned at .1px, it's offsetWidth is 1px larger.
Notes:
The demo comes from this SO post about the issue: <a href="http://stackoverflow.com/q/26124678">http://stackoverflow.com/q/26124678</a>
This bug is also present in Chrome, but not Firefox or IE.
This bug will likely resolve itself if offsetWidth gains support for subpixel values. The Chrome team seems to be working on this, not sure if you guys are as well.</pre>
