I see fractional widths being returned here, but it seems to be drawing rounded to the nearest pixel: http://ephemera.continuation.org/percentage-width.html > Why would they report a width or height that is different than how they are displayed? All browsers that I've tested (the ones listed above, so not IE) report integral values for getBoundingClientRect().width and height (or for left and right in the case of Opera, which doesn't support width and height). > > Firefox often returns non-integral values for getBoundingClientRect().width or height. Sorry, I meant to write "but Firefox", but somehow missed that. Safari, Chrome, and Opera all return values rounded to the nearest pixel. -- Brian
