Editing Help:Editing (section)

=== HTML tags ===
You can use some ''HTML tags'' too.  For a list of HTML tags that are allowed, see Wikipedia's [[Wikipedia:Help:HTML in wikitext|HTML in wikitext]] help page.  In general, you should avoid HTML in favor of Wiki markup whenever possible (see that Wikipedia help page for Wiki markup equivalents to permitted HTML elements, where they exist), as there are already wiki commands for italics, bolding, tables, and other nice things (look on this page for more specifics), and using HTML is much more prone to error.  That said, there are some HTML commands that are useful when editing a wiki, especially on templates (it's usually better to do encapsulate the (relatively) tricky HTML in an easier-to-use template, which can be transcluded in articles).

<strike>Strike out</strike>
or <u>underline</u> text,
or write it <span style=
"font-variant:small-caps">
in small caps</span>.

Please, be ''very sparing'' in your use of the strikethrough tag.

The "span" element can also be used to modify the
<span style="font-family:serif;">font</span>,
<span style="font-size:150%;">size</span>,
and <span style="color:#33aa33;">color</span> of text.

Invisible comments to editors (&lt;!-- --&gt;) 
appear only while editing the page.
<!-- Note to editors: blah blah blah. -->

* If you wish to make comments to the public, you should usually use the talk page.
* Because the comment and anything inside it will be "snipped out" of the page before it gets passed to the renderer, comments can be used judiciously to insert spacing in the source code of a page (to make it easier for editors to read) without affecting the page's final appearance.  See, for example, the lists section in [[#Organizing your writing|Organizing your writing]].

Line breaks<br>can be inserted<br/>with &lt;br&gt; or &lt;br/&gt;

These line breaks can be used to get line breaks in the rendered page without inserting carriage returns into the source code, which is useful for things like lists, where carriage returns interrupt the list numbering (to get white space ''in the code'' without interrupting the list, use HTML comments -- or use both, to get line breaks in the rendered page and white space in the code).
