Notes:

  • Answers will occasionally be moved to the Sandbox archive when there are too many of them. When using them to report bugs, keep an eye on the post.
  • This site, Meta Stack Exchange, is usually used as a "test bed" for pending changes happening to the way text is rendered on all network sites. Changes to text rendering that are going to be rolled out to the network are usually deployed here first to test them out and fix any potential glitches. Currently, there are no such changes pending, but if there were, keep in mind that text posted here may render differently from the other sites until the changes roll out to them as well.

As per Jeff's suggestion in this comment:

You can use this question as a formatting sandbox. You can:

  • edit this question itself (Community Wiki questions such as this one require only 100 reputation to edit instead of 2,000)
  • post answers to this question (This question might be protected, requiring earning 10 reputation on this site to answer)
  • post comments to this question or its answers
  • test suspected bugs with the editor or the rendering
  • post ponies (only when mods are asleep)

Beware that since the changes to syntax highlighting in December 2010, and the inline hints added in March 2011, no syntax highlighting is applied unless the question's tags or an inline hint enable it. So, to test highlighting here in the sandbox:

  1. As of January 8, 2019, you can use GitHub-flavor fenced code blocks in your posts, specifying the language after the opening fence:

    ```html
    While not hinted otherwise: <html></html> source <b>goes</b> "here".
    ```
    
    ```js
    var a = 3;
    while (not (a > 0)) {
        alert("JavaScript code <b>goes</b> here.");
    }
    ```
    
  2. Or:

    • Create code blocks in any way (using the fence notation above, the four-space indent form, or using HTML <pre><code> tags).

    • Save your post.

    • Use your browser's developer tools to edit the resulting HTML. To open developer tools, press F12, or ⌥⌘ I on Mac.

    • Find the <pre> element and add the attribute class="prettyprint", or change it into one of the valid syntax hints linked above, like class="lang-vb prettyprint".

    • Run the following in the location bar: javascript:prettyPrint(); or prettyPrint() in the console.

Answers that are considered annoying or obnoxious, or that cause breakage for users, will be deleted. This is codified as a policy as of March 29, 2018.

  • @BhargavRao When sandbox answers are moved to the archive, comments such as this one -- on the question itself -- aren't migrated; they're deleted. – rgettman Apr 9 '19 at 19:37
  • @rgettman, yeah, that is fine. I had used it for just a small demonstration. The linked answer itself is self-sufficient. Thanks anyway. – Bhargav Rao Apr 9 '19 at 20:22

Test Magic links:

[meta] – link to the current site's Meta; link text is the site name (e.g. "Meta Super User"). Does nothing if the site doesn't have (or already is) a Meta site.

[main] – like [meta], just the other way around.

[edit] – link to the edit page for the post the comment is on, i.e. /posts/{id}/edit. Link text is "edit" (capitalization is respected).

Help center links. Link text for all of these is "help center": [help] should be obvious. [meta-help] links to "What is meta?" (/help/whats-meta) [help/on-topic] links to "What topics can I ask about here?" (/help/on-topic) [help/dont-ask] links to "What types of questions should I avoid asking?" (/help/dont-ask) [help/behavior] links to "What kind of behavior is expected of users?" (/help/behavior).

[tour] and [meta-tour] – equivalent to the FAQ version, but links to the site's Tour page (resp. the meta site's Tour page). Link text is "tour" (capitalization is respected). Legacy names [about] and [meta-about] are still supported.

[ask] – link to the "How to Ask" page

[answer] – link to the "How to Answer" page.

Links to the front page of Stack Exchange sites (link text is the site name): [so] – link to Stack Overflow [su] – link to Super User [sf] – link to Server Fault [metase]/[meta.se] – link to Meta Stack Exchange [ubuntu.se] – link to Ask Ubuntu [mathoverflow.se] – link to MathOverflow [a51] – link to Area 51 [se] – link to the Stack Exchange Localized Stack Overflow sites can be linked as [es.so] – link to Stack Overflow en español [ja.so] – link to スタック・オーバーフロー [pt.so] – link to Stack Overflow em Português [ru.so] – link to Stack Overflow на русском All other Stack Exchange sites, except Stack Apps: [something.se] – link to something.stackexchange.com, if that site exists. Link text is the site name. [sitename.meta.se] or [meta.sitename.se] – link to a site-specific Meta site. Link text is "Meta ".

[chat] – link to the current site's chat site ne showing a list of active rooms from the referring site), the link text being "{site name} Chat".

On Stack Overflow and localized Stack Overflow sites: [mcve], [reprex], [repro], [mre] and [example] – link to the Minimal Complete & Verifiable Example page for the site.

Tags (these work in questions, answers, comments, and chat, but are not formatted as tags in comments): [Note that if you're on meta, will still point to the main site. Except on Meta Stack Exchange, which doesn't have a main, makes no difference from .] creates a link to the named tag on the main site. creates a link to a tag on meta. The text is linked

Supported magic links in chat

In chat, only a limited subset of the magic links listed for comments work, plus one chat-specific magic link.

Chat supports the following magic links: [meta], [main], [ask], [answer], all the links to specific sites, and tag links (with tag formatting). Chat also adds [chat-faq], which results in "chat faq".

The tag magic links work as expected on Stack Overflow Chat and Meta Stack Exchange Chat. However, on Stack Exchange Chat, the chat room in which you use the magic link must be associated with a specific Stack Exchange site, and will take on the formatting of tags on that site.

      I’m testing hyphens ("HYPHEN MINUS") on iOS 12. Specifically, typing multiple hyphens into the edit box. Typing 2 hyphens together results in a single "EM DASH".

      Related question on the Ask Different Stack:
      How do I type a hyphen in iOS 12?

      The text in parentheses describes the resulting string after typing N hyphens.

      Below this line is a single “hyphen” (HYPHEN)

      -

      Below this are 2 hyphens (EM DASH)

      And 3 hyphens (EM DASH + HYPHEN)

      —-

      Four hyphens (EM DASH + EM DASH)

      ——

      -—

      Five hyphens (EM DASH + EM DASH + HYPHEN)

      ——-

      Long press and second character (EN DASH)

      Long press and third character (EM DASH)

      Copy/paste




      Hello -

      • (BULLET - Long press and first character)

      Saying "hyphen hyphen hyphen hyphen" results in 4 contiguous hyphens


      Saying "dash" results in an "EN DASH" and "dash dash dash dash" results in 4 x "EN DASH + SPACE" (not contiguous).

      Does LaTeX formatting work? Let me test.

      \binom{20}{2} \cdot (\frac{1}{10})^2 \cdot (\frac{9}{10})^{18} \approx 28.518%

      Cool! It does! Ok
