HTML Tags You Can Use on GitHub

Wherever HTML is rendered on GitHub (gists, README files in repos, comments on issues and pull requests, ...) you can use any of the HTML elements that GitHub Flavored Markdown (GFM) provides syntactic sugar for. You can either use the syntactic sugar that GFM (or other GitHub-supported markup language you're using) provides or, since Markdown can contain raw HTML, you can enter the HTML tags manually.

But GitHub also allows you to use a few HTML elements beyond what Markdown provides by entering the tags manually, and some of them are styled with CSS. Most raw HTML tags get stripped before rendering the HTML. Those tags that can be generated by GFM syntactic sugar, plus a few more, are whitelisted. These aren't documented anywhere that I can find. Here's what I've discovered so far:

Edit — February 2019

This gist had a far larger impact than I imagined it would, and apparently people are still finding it, so a quick update:

• TC39 is currently moving forward with a slightly different version of TLA, referred to as 'variant B', in which a module with TLA doesn't block sibling execution. This vastly reduces the danger of parallelizable work happening in serial and thereby delaying startup, which was the concern that motivated me to write this gist
• In the wild, we're seeing (async main(){...}()) as a substitute for TLA. This completely eliminates the blocking problem (yay!) but it's less powerful, and harder to statically analyse (boo). In other words the lack of TLA is causing real problems
• Therefore, a version of TLA that solves the original issue is a valuable addition to the language, and I'm in full support of the current proposal, which you can read here.

I'll leave the rest of this document unedited, for archaeological

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
