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.

Element APIs

Getting box metrics

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

Did you see my talk about strace? Do you want to know more? Here's your chance!

If you didn't, and you want to watch it, go watch it! Spying on your programs with strace

more strace resources (Linux-only)

• I've written tons of blog posts about strace. I'm a little bit obsessed. You can read them at http://jvns.ca/blog/categories/strace/. If you want an introduction, start with Debug your programs like they're closed source.
• Strace - The Syadmin's Microscope and Strace: The Lost Chapter are both excellent articles by Greg Price
• Brendan Gregg has an excellent article about how strace will slow your processes down, and when it's not appropriate to use it
