Inside Chrome, when setting a <div> tag with min-height = 1000px and then adjusting the page-zoom level, the offsetHeight/clientHeight report 1-2 px less than the min-height: 100% scale: document.getElementById('box').offsetHeight Returns: 1000 83% scale: document.getElementById('box').offsetHeight Returns: 999 69% scale: document.getElementById('box').offsetHeight 57% scale: document.getElementById('box').offsetHeight Returns: 998 This issue affects the JQuery UI, which depends on a fixed pixel width to determine whether the browser can support the min-height property.

This no longer reproduces, was likely fixed by subpixel layout.
