Formatting Sandbox

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.

You may also want to take a look at the Stack Exchange's Sandbox chat room

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:

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.");
}
```

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.

# The Comprehensive Formatting Test

## Supported Markdown

Stack Exchange maintains its own [Markdown Help][one] page.  It maintains a subset containing most, but not all [markdown features][two].

### Code Formatting

- Inline code formatting or code spans
    - To place code inline, enclose your code in a pair of backtick characters (`` ` ``).  In the editor, you can highlight a portion of text in a single line and either press <kbd>Ctrl</kbd>-<kbd>k</kbd> or press the `{}` toolbar button.

            Use the line `System.out.println("Hello World!");`.

        Use the line `System.out.println("Hello World!");`.

    - Escape a backtick within inline code by enclosing the inline code with double-tickmarks:

            Within code: ``for line in `someCommand` ``

        Within code: ``for line in `someCommand` ``

    - A single backtick character in a line won't form a code block.

            The backtick character is '`'

        The backtick character is '`'.

    -   To escape multiple backtick characters in a line, without forming a code block, escape the first with a backslash character:

            There are two backtick characters ('\`') in this line ('`').

        There are two backtick characters ('\`') in this line ('`').

    - Outside of a code block, you can always escape any backtick character.

            There are two backtick characters ('\`') in this line ('\`').

        There are two backtick characters ('\`') in this line ('\`').

    - Use the same number of backticks, before and after a span, to escape any backticks within:

            ```````` Escaped `` backticks `! ````````

        ```````` Escaped `` backticks `! ````````

- Block code formatting
    - To place a code block, indent the lines containing your code by 4 space characters.  In the editor, you can highlight lines of text and either press <kbd>Ctrl</kbd>-<kbd>k</kbd> or press the `{}` toolbar button.

        ```
            System.out.println("Hello World!");
            System.out.println("Code Block!");
        ```

            System.out.println("Hello World!");
            System.out.println("Code Block!");

    - One may also place a [code fence][three], which is 3 or more backtick or tilde characters, each on their own line, before and after the code.

        ~~~
        ```
        System.out.println("Hello World!");
        System.out.println("Code Fence with backticks!");
        ```
        ~~~

        ```
        System.out.println("Hello World!");
        System.out.println("Code Fence with backticks!");
        ```

        <br>

        ```
        ~~~
        System.out.println("Hello World!");
        System.out.println("Code Fence with tildes!");
        ~~~
        ```

        ~~~
        System.out.println("Hello World!");
        System.out.println("Code Fence with tildes!");
        ~~~

        <br>

        ````````````````````
        ~~~~~~~~~~~~~~~~~~~~
        System.out.println("Hello World!");
        System.out.println("Code Fence with 20 tildes!");
        ~~~~~~~~~~~~~~~~~~~~
        ````````````````````

        ~~~~~~~~~~~~~~~~~~~~
        System.out.println("Hello World!");
        System.out.println("Code Fence with 20 tildes!");
        ~~~~~~~~~~~~~~~~~~~~

- HTML and other markdown are not supported within code spans or code blocks.

    ~~~
    ```
    <code> *Not in code!* </code>
    ```
    ~~~

    ```
    <code> *Not in code!* </code>
    ```

### Line Breaks

- Simply placing one line break doesn't produce a line break when rendered.

    ```
    This is one line.
    This was intended to be on the next line, but it appears on the same line.
    ```

    This is one line.
    This was intended to be on the next line, but it appears on the same line.

- Using one or more blank lines produces a paragraph break.

    ```
    This is one paragraph.  It has some sentences.

    This is intended to be a second paragraph.
    ```

    This is one paragraph.  It has some sentences.

    This is intended to be a second paragraph.

- Use two spaces at the end of a line to force a line break.

    ```
    This is one line.  
    This is intended to be on the next line.
    ```

    This is one line.  
    This is intended to be on the next line.


- Use an HTML `<br>` tag to produce a line break.

    ```
    This is one line.<br>
    This is intended to be on the next line.
    ```

    This is one line.<br>
    This is intended to be on the next line.

### Italics and Bold

- Surround text with exactly one underscore (`_`) or one asterisk (`*`) to render text in _italics_.

    `This is _italic_ text.  This is *italic* too.`

    This is _italic_ text.  This is *italic* too.

- Surround text with exactly two underscores (`__`) or two asterisks (`**`) to render text in __bold__.

    `This is __bold__ text.  This is **bold** too.`

    This is __bold__ text.  This is **bold** too.

- Surround text with both of the above to render text in __*bold and italic*__.

    `___underscores only___ and ***asterisks only*** and __*underscore and asterisk*__ and **_asterisk and underscore_**.`

    ___underscores only___ and ***asterisks only*** and __*underscore and asterisk*__ and **_asterisk and underscore_**.

- 3 or more and odd does both bold and italic.  4 or more and even does bold only.  Using both `_` and `*` for the same purpose: outside ones count, inside ones ignored.

    `****Four!****`

    ****Four!****

    `_____Five!_____`

    _____Five!_____

    `______Six!______`

    ______Six!______

    `*******Seven!*******`

    *******Seven!*******

    `**__Two and Two!__**`

    **__Two and Two!__**

    `_*One and One!*_`

    _*One and One!*_

### Headers

- The number of `#` characters determines the header level, from 1-6.  Any `#` characters at the end of the line are not rendered.  Above six `#`'s are no longer treated as a header and rendered as plain text.
    #### Headings following a paragraph
    `# Heading 1 ###`

    # Heading 1 ###

    `## Heading 2 ####################`

    ## Heading 2 ####################

    `### Heading 3`

    ### Heading 3

    `#### Heading 4`

    #### Heading 4

    `##### Heading 5`

    ##### Heading 5

    `###### Heading 6`

    ###### Heading 6

    `####### Heading 7`

    ####### Heading 7

    #### Headings following a heading use different top-margin spacing
    # Heading 1
    ## Heading 2
    ### Heading 3
    #### Heading 4
    ##### Heading 5
    ###### Heading 6
    ####### Heading 7



- Alternates for headers 1 and 2

    - Use equals signs under the header text for heading 1.

        ```
        Equals Signs!
        ===
        ```

        Equals Signs!
        ===

    - Use dashes under the header text for heading 2.

        ```
        Dashes!
        ---
        ```

        Dashes!
        ---

     - The triple bar ≡ doesn't seem to do anything special here.

        ```
        Triple Bar!
        ≡≡≡
        ```

        Triple Bar!
        ≡≡≡


- Escape `#` with a backslash or use the HTML entity instead.

    `\# Not a heading`

    \# Not a heading

    `&#35; Not a heading`

    &#35; Not a heading

    `# Heading ending with hashtag &#35;`

    # Heading ending with hashtag &#35;

- Italic headers

    `# _Italic_ *Header* #`

    # _Italic_ *Header* #

### Horizontal Rules

- Use 3 or more hyphens, asterisks, or underscores by themselves on a line.  Pressing <kbd>Ctrl</kbd>-<kbd>R</kbd> inserts a horizontal rule for you.

    ```
    ---
    ***
    ______
    ```
    <kbd>Ctrl</kbd>-<kbd>R</kbd>

    ---
    ***
    ______
    

----------


- Single spaces between the characters still works.

    ```
    - - -
    * * *
    _ _ _ _ _ _
    ```

    - - -
    * * *
    _ _ _ _ _ _

- Multiple spaces *still* works!

    ```
    -  -  -
    *   *   *
    _    _    _    _    _    _
    ```

    -  -  -
    *   *   *
    _    _    _    _    _    _

- Even irregular spacing is fine

    ```
    -   -          -
    *    *       *
    _    _      __      _                   _
    ```

    -   -          -
    *    *       *
    _    _      __      _                   _

### Blockquotes

- Use `>` or highlight text and press <kbd>Ctrl</kbd>-<kbd>Q</kbd> to create a blockquote.

    `> Quoting something else`

    > Quoting something else

    `>No space between > and text`

    >No space between > and text

- One can nest blockquotes with multiple `>` characters.

    ```
    > First level!
    >> Second level!
    >>> Third level!
    >>
    >> Need blank line and one less < to go back to second.
    >
    > Same idea for back to first.
    ```

    > First level!
    >> Second level!
    >>> Third level!
    >>
    >> Need blank line and one less < to go back to second.
    >
    > Same idea for back to first.

- Escape a `>` character with a backslash.

    ``\> I want a `>`!``

    \> I want a `>`!

- Markdown works within a blockquote.

    ```
    > Enjoy **this** `unicorn`!
    >
    > ![image of a unicorn](https://i.sstatic.net/7I1jg.jpg)
    ```

    > Enjoy **this** `unicorn`!
    >
    > ![image of a unicorn](https://i.sstatic.net/7I1jg.jpg)

- Code formatting works within a blockquote.  Indenting requires 5 spaces: 1 for the blockquote, and 4 for the code indention.

    ```
    >     System.out.println("Hello World!");

    > Inline: `System.out.println("Hello World!");`

    > Code fence:
    > ```
    > System.out.println("Hello World!");
    > ```
    ```

    >     System.out.println("Hello World!");

    > Inline: `System.out.println("Hello World!");`

    > Code fence:
    > ```
    > System.out.println("Hello World!");
    > ```

### Lists

- #### Unordered Lists
    - Use `+`, `-`, or `*`, followed by a space character.  Or press <kbd>Ctrl</kbd>-<kbd>U</kbd> or press the bulleted list icon in the editor toolbar.

        ```
        + One
        - Two
        * Three
        ```

        + One
        - Two
        * Three

    - Spaces are necessary.

        ```
        +Necessary
        ```

        +Necessary

    - The other main arithmetic operators don't create lists.

        ```
        / No
        % No
        ^ No
        = No
        ```

        / No
        % No
        ^ No
        = No

- #### Ordered Lists
    - Use any number, followed by a period ("dot"), then a space character, or any .  Or press <kbd>Ctrl</kbd>-<kbd>O</kbd> or press the numbered list icon in the editor toolbar.

        ```
        1. One
        10. Two
        42. Three
        ```

        1. One
        10. Two
        42. Three

    - `#)` also works.

        ```
        1) One
        10) Two
        42) Three
        ```

        1) One
        10) Two
        42) Three

    - Spaces are necessary.

        ```
        1.Necessary
        1.Necessary
        ```

        1.Necessary
        1.Necessary
   
    - The period ("dot") is necessary.

        ```
        1 Necessary
        1 Necessary
        ```

        1 Necessary
        1 Necessary

    - Can have a different starting number:

        ```
        50. fifty
        51. fifty-one
        52. fifty-two
        ```

        50. fifty
        51. fifty-one
        52. fifty-two



    - At most nine digits for the number

      `1. One`

        1. One

      `12. Two`

        12. Two

      `123. Three`

        123. Three

      `1234. Four`

       1234. Four

      `12345. Five`

        12345. Five

      `123456. Six`

        123456. Six

      `1234567. Seven`

        1234567. Seven

      `12345678. Eight`

        12345678. Eight

      `123456789. Nine`

        123456789. Nine

      `1234567890. Ten`

        1234567890. Ten




- Multiple lines within list items: indent 4 spaces, or do we need to?

```
1. Same line
    Continuation of the same line

    Continuation of the same line
```

<br>

- Code within list items: indention requires blank line then 4 additional spaces beyond list indention level.

~~~

- One can control the horizontal alignment by placing a colon (:) in the separator line -- first character for left, first and last for center, and last for right.

    ```
    |Left-aligned|Center-aligned|Right-aligned|
    |:-----------|:------------:|------------:|

- Long-enough content will wrap.

    | Wrap |
    | ---- |
    | This content is long enough to wrap because it contains a lot of words meant to cause the table content to wrap to another line. |

- Content that is too long without a line break produces a horizontal scrollbar.

## Stack Exchange Extensions to Markdown

### Tags

- Enclose in brackets `[]` and text is prefixed with `tag:`.  Letters get lowercased.  They link to the main site's tag page for that tag.

        [tag:mytag] [tag:UPPERCASE] [tag:with1number]

    [tag:mytag] [tag:UPPERCASE] [tag:with1number]

- Allowed characters: alphanumeric plus limited punctuation: Individual `-`, `#`, `.`. and `+` characters are allowed.

        [tag:abcdefghijklmnopqrstuvwxyz-#.+ABCEDFGHIJKLMNOPQRSTUVWXYZ0123456789]

    [tag:abcdefghijklmnopqrstuvwxyz-#.+ABCEDFGHIJKLMNOPQRSTUVWXYZ0123456789]

    - Leading and trailing `-` are stripped off, but the tag still forms.

            [tag:c-] [tag:c--] [tag:-c] [tag:--c] [tag:-----c] [tag:c-------]

        [tag:c-] [tag:c--] [tag:-c] [tag:--c] [tag:-----c] [tag:c-------]

    - Trailing `.` are stripped off, but the tag still forms.

            [tag:c.] [tag:c..] [tag:.c] [tag:..c] [tag:.....c] [tag:c.......]

        [tag:c.] [tag:c..] [tag:.c] [tag:..c] [tag:.....c] [tag:c.......]

    - Leading `#` are stripped off, but the tag still forms.

            [tag:c#] [tag:c##] [tag:#c] [tag:##c] [tag:#####c] [tag:c#######]

        [tag:c#] [tag:c##] [tag:#c] [tag:##c] [tag:#####c] [tag:c#######]

- The `+` character is allowed. If there's only 1 in the middle, it will not render in the preview, but it will show up in the post.  If there are at least 2 of them, they'll show up in the preview and the post.

        [tag:abc+def] [tag:abc++def] [tag:abc++++++++++++++++++++def]

    [tag:abc+def] [tag:abc++def] [tag:abc++++++++++++++++++++def]

    - Leading `+` are stripped off, but the tag still forms.

            [tag:c+] [tag:c++] [tag:+c] [tag:++c] [tag:+++++c] [tag:c+++++++]

        [tag:c+] [tag:c++] [tag:+c] [tag:++c] [tag:+++++c] [tag:c+++++++]

- Meta-tags: Use the `meta-tag:` prefix.  They link to the meta site's tag page for that tag.

        [meta-tag:waffles]

    [meta-tag:waffles]

    - Certain meta tag names are given special styling.

        [meta-tag:bug] [meta-tag:discussion] [meta-tag:feature-request] [meta-tag:support]

        [meta-tag:community-ads] [meta-tag:company-update] [meta-tag:faq] [meta-tag:featured] [meta-tag:mod-agreement-policy] [meta-tag:product-discovery] [meta-tag:status-bydesign] [meta-tag:status-completed] [meta-tag:status-declined] [meta-tag:status-deferred] [meta-tag:status-norepro] [meta-tag:status-planned] [meta-tag:status-review] [meta-tag:status-wontfix]

        - [meta-tag:status-reproduced] is apparently no longer given special styling.

- Certain words, regardless of case, don't form tags, regardless of capitalization or whether it's a meta tag.  There are no other words, 4 letters or less, that don't form tags.  The words "and" and "or" won't form tags.  In preview, "not" won't form a tag but the actual post will render it.  The preview renders them as the text is, e.g. `[tag:Or]` but the post will render it `or`.

    ```
    [tag:an] [tag:and] [tag:AND] [tag:band]
    [tag:no] [tag:not] [tag:noT] [tag:note]
    [meta-tag:o] [meta-tag:or] [meta-tag:Or] [meta-tag:ore]
    [tag:and-not-or]
    ```

    [tag:an] [tag:and] [tag:AND] [tag:band]
    [tag:no] [tag:not] [tag:noT] [tag:note]
    [meta-tag:o] [meta-tag:or] [meta-tag:Or] [meta-tag:ore]
    [tag:and-not-or]

### Syntax Highlighting

- Where it's [supported](https://meta.stackexchange.com/questions/184108/what-is-syntax-highlighting-and-how-does-it-work/184109#184109), insert an HTML comment specifying the language for the following code block immediately following it.  Subsequent code blocks are not highlighted unless they have their own syntax highlighting specified.  (Sites such as Stack Overflow will infer the syntax highlighting from tags on the question, rendering this hint unnecessary.)

```

        
    System.out.println("Hello World!");

<br>

    System.out.println("Not highlighted.");
```


        
    System.out.println("Hello World!");

<br>

    System.out.println("Not highlighted.");

- Use `language-all` to highlight subsequent code blocks.

```

        
    System.out.println("Hello World!");

<br>

    System.out.println("Highlighted.");
```


        
    System.out.println("Hello World!");

<br>

    System.out.println("Highlighted.");

- Others besides Java


```

        
    echo "Hello World!"
```


        
    echo "Hello World!"


```

        
    printf("Hello World!\n");
```


        
    printf("Hello World!\n");


```

        
    std::cout << "Hello World!" << std::endl;
```


        
    std::cout << "Hello World!" << std::endl;


```

        
    Console.WriteLine("Hello World!");
```


        
    Console.WriteLine("Hello World!");

```

        
    console.log("Hello World!");
```


        
    console.log("Hello World!");


```

        
    {
        "message":"Hello World!"
    }
```


        
    {
        "message":"Hello World!"
    }


```

        
    print "Hello World!\n";

```


        
    print "Hello World!\n";


```

        
    print("Hello World")

```


        
    print("Hello World")


```

        
    puts "Hello World!"

```


        
    puts "Hello World!"

- Code fence language hint



~~~
```java
System.out.println("code fence highlighting");
```
~~~

```java
System.out.println("code fence highlighting");
```

You can also use `lang-default` to let the highlighter guess about what language to use.

### MathJax
MathJax is [only available on some sites](https://meta.stackexchange.com/q/216606/271271), which doesn't include Meta Stack Exchange.

There are two format varieties used.

On [Mathematics](https://math.stackexchange.com/) the code:
```
$\LaTeX$
```

Would produce the following HTML:

That HTML would then be converted in-browser by MathJax JavaScript code to the stylized ![LaTeX logo generated by MathJax](https://i.sstatic.net/jdZhJ.png). Here on Meta Stack Exchange, it produces:

### Editable schematics
Editable schematics are only available on some sites, which doesn't include Meta Stack Exchange.

<pre><code>
&lt;!-- Begin schematic: In order to preserve an editable schematic, please
     don't edit this section directly.
     Click the "edit" link below the image in the preview instead. --&gt;

![schematic](https://i.sstatic.net/9DUDp.png)

&lt;!-- End schematic --&gt;
</code></pre>



![schematic](https://i.sstatic.net/9DUDp.png)



When enabled, it will produce HTML similar to:
```
<p><img src="https://i.sstatic.net/9DUDp.png" alt="schematic"></p>

<p><sup><a href="/plugins/schematics?image=http%3a%2f%2fi.stack.imgur.com%2f9DUDp.png">simulate this circuit</a> &ndash; Schematic created using <a href="https://www.circuitlab.com/" rel="nofollow">CircuitLab</a></sup></p>
```

## Allowed HTML

Only some [basic HTML elements are whitelisted](https://meta.stackexchange.com/questions/1777/what-html-tags-are-allowed-on-stack-exchange-sites).  Also, only some attributes within those tags are whitelisted as well.  If specified, they must be in order!  Those that don't meet these requirements are completely stripped from the content.

The answer seems to miss a link format: Simply put [some link] into the text and add [some link]: https://https://meta.stackexchange.com somewhere else. Essentially a reference link where Display==refName. Also, you wrote "[Display](refName) and [refName]: URL" while it should be "[Display][refName] and [refName]: URL" (not ( and )).
