How do I display HTML code (entities) on a web page?

Question

how do you write html code so the user and see it on a webpage (like a how-to for html)

Answer 1

encode your html entities:

< … &lt;
> … &gt;
& … &amp;
" … &quot;
(' … &apos; xml, not html. see comments)

you might also want to use

<pre><code>
here comes your preformatted and escaped &lt;html&gt;-code
</code></pre>

to have your code monospaced and preserve whitespaces

Answer 2

You have to use HTML character entities < and > in place of the < and > symbols so they aren't interpreted as HTML tags.
