Gist markdown examples

Todo

Reformat this whole document and assimilate these:

A list of GitHub emoji markup, adapted from rxavier's Complete list of github markdown emoji markup, generated with a Grunt script for maintainability (see repository).

Additional original source material: http://unicode.org/emoji/charts/full-emoji-list.html

This table is available as a gist at https://gist.github.com/GerHobbelt/b9b87a2257ddd5251a45628d61385717 and as part of the build repo at https://github.com/GerHobbelt/emoji-list/blob/master/dist/emoji-list.md

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()
