laws of computer programming

• any given program, when running, is obsolete.
• if a program is useless, it will have to be documented.
• if a program is useful, it will have to be changed.
• any program will expand to fill all available memory.
• the value of a program is proportional to the weight of its output.
• program complexity grows until it exceeds the capability of the programmer to maintain it.
• make it possible for programmers to write in english and you will find that programmers cannot write in english.

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
