What is meta? ×
Meta Stack Exchange is where users like you discuss bugs, features, and support issues that affect the software powering all 131 Stack Exchange communities.

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 100 reputation to edit) - minor edit updated
  • post answers to this question (Since this question is protected this requires earning 10 reputation on this site)
  • post comments to this question or its answers

Beware that since the changes to syntax highlighting in December 2010, and the inline hints added 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. Set some language tags to this question:

    • See the explanation and the list of languages.

    • Adding clashing tags, such as both and , enforces a fallback to default, which is different from "no highlighting". (These tags are currently set on this question.)

  2. Or: on the start of a line, specify a language inline using <!-- language: lang --> hints, and indent the code 4 spaces as usual. There is a full list of hints (scroll down a little).

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

    • Save your post.

    • Use something like Firebug (Firefox), Web Inspector (Safari, Chrome) or Developer Tools (Internet Explorer 8) to edit the resulting HTML. To open Chrome Dev Tools, press F12

    • Find the <pre> element and add the attribute class="prettyprint", or change it into something more specific, like class="lang-vb prettyprint".

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

This is an answer which shows that using 2 spaces doesn't format as code:

This is a line with two spaces before it.

This is a line with four spaces before it.

Some apparent whitespace problems, 10 m/s (original post):

The period of a pendulum of length $h$ for small oscillations is $2\pi \sqrt{h/g}$, with $g$ the acceleration due to gravity, about $10 m/s$.

Source:

Update: Meta Stack Overflow does not seem to have the formula stuff that Physics has.

Be aware that you can run into trouble if you try to use < inside: <code>a<b</code> gives a!


  1. You can't have a backslash \ in the end of inline code in comments. If you try `\\`, then the result will be `\`. You'll have to type `\\ ` and live with the white space being within the inline code.

And here's the second -- perhaps as a new post.

Okay so far, will try one more time...

Unix time, or POSIX time, is a system for describing points in time, defined as the number of seconds elapsed since midnight proleptic Coordinated Universal Time (UTC) of January 1, 1970, not counting leap seconds. It is used widely, not only in Unix-like operating systems, but also in many other computing systems and file formats. It is neither a linear representation of time nor a true representation of UTC (though it is frequently mistaken for both), as it cannot represent standard UTC leap seconds (e.g. December 31, 1998 23:59:60), although otherwise the times it represents are UTC. –  Yi Jiang Oct 31 '10 at 8:30

HTML markup won't work in SO.. testing it here.

<a title="jhddj" rel="relImageStatusUpdate" href="<%= format_status_image_url(row["UserID"],row["USERSTATUS_ID"]) %>" 
id="ahrefStatusImage">

Trying pure HTML without the ASP.NET stuff:
