For many HTML elements, more convenient wikitext code is available, see [[Help:Editing]]. On the other hand, HTML tags allow an <ttcode>id</ttcode> attribute that can be referenced in one's [[Help:User style|user style]] CSS, and allows the tagelement to be used as link target.

For many HTML elements, more convenient wikitext code is available, see [[Help:Editing]]. On the other hand, HTML tags allow an <tt>id</tt> that can be referenced in one's [[Help:User style|user style]] CSS, and allows the tag to be used as link target.

: <code><nowiki><a href="http://meta.wikimedia.org/">Main Page</a></nowiki></code>

For example, the anchor element <tt>&lt;a></tt> is not allowed, so the wikitext

: <code><nowiki><a href="http://meta.wikimedia.org/">Main Page</a></nowiki></code>

is treated like the wikitext

: <code><nowiki>&amp;lt;a href="http://meta.wikimedia.org/"&amp;gt;Main Page&amp;lt;/a&amp;gt;</nowiki></code>

: <code><nowiki>&amp;lt;a href="http://meta.wikimedia.org/"&amp;gt;Main Page&amp;lt;/a&amp;gt;</nowiki></code>

and is therefore displayed as

: {{Quote|1=<a href="http://meta.wikimedia.org/">Main Page</a>}}

which is unlikely to be what the editor intended. Instead of using the anchor element (&lt;a&gt;) the wiki markup for external reference is recommendedrequired (enclosed in square brackets with the URL separated from the contents by a single space):

: <a href="http://meta.wikimedia.org/">Main Page</a>

: <code><nowiki>[http://meta.wikimedia.org/ Main Page]</nowiki></code>

which is unlikely to be what the editor intended. Instead of using the anchor element (&lt;a&gt;) the wiki markup for external reference is recommended (enclosed in square brackets with the URL separated from the contents by a single space):

displays as:

: {{Quote|[http://meta.wikimedia.org/ Main Page]}}
