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

Question

how do you write html code so that the user can see it on a web page (for example, as for html)

Answer 1

encode your html objects:

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

you can also use

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

so that your code is monospaced and retains spaces

Answer 2

You must use the HTML symbol characters <and >instead of <and>, so they are not interpreted as HTML-tags.

Answer 3

', '.
