Display HTML snippets in HTML

The tried and true method for HTML:

  1. Replace the & character with &
  2. Replace the < character with &lt;
  3. Replace the > character with &gt;
  4. Optionally surround your HTML sample with <pre> and/or <code> tags.

best way:

<xmp>
// your codes ..
</xmp>

old samples:

sample 1:

<pre>
  This text has
  been formatted using
  the HTML pre tag. The brower should
  display all white space
  as it was entered.
</pre>

sample 2:

<pre>
  <code>
    My pre-formatted code
    here.
  </code>
</pre>

sample 3: (If you are actually "quoting" a block of code, then the markup would be)

<blockquote>
  <pre>
    <code>
        My pre-formatted "quoted" code here.
    </code>
  </pre>
</blockquote>

nice CSS sample:

pre{
  font-family: Consolas, Menlo, Monaco, Lucida Console, Liberation Mono, DejaVu Sans Mono, Bitstream Vera Sans Mono, Courier New, monospace, serif;
  margin-bottom: 10px;
  overflow: auto;
  width: auto;
  padding: 5px;
  background-color: #eee;
  width: 650px!ie7;
  padding-bottom: 20px!ie7;
  max-height: 600px;
}

How to highlight source code in HTML?


is there a tag for don't render HTML until you hit the closing tag?

No, there is not. In HTML proper, there’s no way short of escaping some characters:

  • & as &amp;
  • < as &lt;

(Incidentally, there is no need to escape > but people often do it for reasons of symmetry.)

And of course you should surround the resulting, escaped HTML code within <pre><code>…</code></pre> to (a) preserve whitespace and line breaks, and (b) mark it up as a code element.

All other solutions, such as wrapping your code into a <textarea> or the (deprecated) <xmp> element, will break.1

XHTML that is declared to the browser as XML (via the HTTP Content-Type header! — merely setting a DOCTYPE is not enough) could alternatively use a CDATA section:

<![CDATA[Your <code> here]]>

But this only works in XML, not in HTML, and even this isn’t a foolproof solution, since the code mustn’t contain the closing delimiter ]]>. So even in XML the simplest, most robust solution is via escaping.

1 Case in point:

textarea {border: none; width: 100%;}
<textarea readonly="readonly">
  <p>Computer <textarea>says</textarea> <span>no.</span>
</textarea>

<xmp>
  Computer <xmp>says</xmp> <span>no.</span>
</xmp>
