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

Box metrics

elem.offsetLeft, elem.offsetTop, elem.offsetWidth, elem.offsetHeight, elem.offsetParent
elem.clientLeft, elem.clientTop, elem.clientWidth, elem.clientHeight
elem.getClientRects(), elem.getBoundingClientRect()

According to Brad Stulberg and Steve Magness, who write about the accomplishments of elite athletes in their new book Peak Performance, there’s a simple phenomenon that allows people to overcome their fears and limitations: a concept called self-transcendence.

While researching their book, Stulberg and Magness interviewed countless scientists and world-renowned athletes. They found that people who exhibited this kind of “superhuman” strength were able to do so only when they chose to focus on a purpose greater than themselves.

	Stulberg and Magness refer to this paradigm shift as “ego minimization.” They point to a recent study published in Proceedings of the National Academy of Sciences, where researchers used fMRI scans to see what happens inside the brain of people presented with threatening messages.
