HTML5 <details> in GitHub

Using <details> in GitHub

Suppose you're opening an issue and there's a lot noisey logs that may be useful.

Rather than wrecking readability, wrap it in a <details> tag!

<details>
 <summary>Summary Goes Here</summary>
 ...this is hidden, collapsable content...
</details>

https://developer.mozilla.org/en-US/docs/Web/HTML/Element/details

Example

Hey guys, I just this problem with Node v4.1.1. Apparently you can't require files that don't exist! plz fix.

Stack Trace for `require('does.not.exist')` ```shell require('does.not.exist') Error: Cannot find module 'does.not.exist' at Function.Module._resolveFilename (module.js:336:15) at Function.Module._load (module.js:286:25) at Module.require (module.js:365:17) at require (module.js:384:17) at repl:1:1 at REPLServer.defaultEval (repl.js:164:27) at bound (domain.js:250:14) at REPLServer.runBound [as eval] (domain.js:263:12) at REPLServer.

Note that the <details> triangle will not be visible in Firefox with GitHub's current CSS, so it won't be obvious that it is clickable.

I recently created a userscript that will collapse long blocks of code and quote blocks for times when people don't use <details>... currently it adds a clickable <div> to toggle the content; I thought about using a details > summary wrapper, but it doesn't seem to be working in my Firefox browser...

See https://gist.github.com/ericclemmons/b146fe5da72ca1f706b2ef72a20ac39d

This is how the spec says things are supposed to work. In particular, https://html.spec.whatwg.org/multipage/rendering.html#the-details-and-summary-elements describes default styles for summary that cause the disclosure triangle to be rendered as long as the summary is display:list-item.

I don't think Chromium has updated to the new (first?) spec rules for how the disclosure triangle interacts with style.

So it seems that per the current requirements in the HTML spec, Firefox is behaving as expected by not displaying the disclosure triangle, and Chrome by displaying it is not conforming to the requirements.

And Firefox actually starts supporting <details>/<summary> since Firefox 49.

The Firefox (49+) arrow issue should be resolved with necolas/normalize.css#604.
Looks like the Chromium team is also looking to resolve the spec issue: https://bugs.chromium.org/p/chromium/issues/detail?id=590014.

@silverwind I'm using Firefox, and I can see the arrow, so I guess it's fixed now.

It seems like Markdown is no longer parsed inside details tags

For example ```sh echo What happened? ```

Markdown's supported, as long as you have a blank line between the </summary> tag and the following content. Apparently kramdown is very sensitive to missing blank lines.

Without blank lines ... formatting like _italics_, **bold**, etc. all fail, just because there's a missing line. > Blockquote without a precending blank line is assumed to belong to the previous line ``` and the same with code blocks. ```
With blank lines

... formatting like italics, bold, linking and monotype works.

Blockquote works!

Code works!

As always, the Preview tab is your friend.

Just played a bit to see formatting issue on summary line. Consider two examples below.

With blank line after <summary> open tag:

**Summary** Goes `Here`
 ...this is hidden, collapsable content...

Without blank line after <summary> open tag:

Summary Goes Here

 ...this is hidden, collapsable content...
