What forces layout / reflow

All of the below properties or methods, when requested/called in JavaScript, will trigger the browser to synchronously calculate the style and layout*. This is also called reflow or layout thrashing, and is common performance bottleneck.

Generally, all APIs that synchronously provide layout metrics will trigger forced reflow / layout. Read on for additional cases and details.

Element APIs

Getting box metrics

• elem.offsetLeft, elem.offsetTop, elem.offsetWidth, elem.offsetHeight, elem.offsetParent

Super Form Reset

A couple of things to watch out for:

- IE8: If a text input doesn't have padding on all sides or none the text won't be centered.
- The default border sizes on text inputs in all UAs seem to be slightly different. You're better off using custom borders.
- You NEED to set the font-size and family on all form elements
- Search inputs need to have their appearance reset and the box-sizing set to content-box to match other UAs
