Permitted HTML
The following HTML elements are currently permitted:

The following excerpt from OutputPage.php additionally shows which attributes are allowed. For many HTML elements, more convenient wikitext code is available, see Help:Editing. On the other hand, HTML tags allow an id that can be referenced in one's user style css, and allows the tag to be used as link target.
/* private */ function removeHTMLtags( $text ) { wfProfileIn( "OutputPage::removeHTMLtags" ); $htmlpairs = array( # Tags that must be closed "b", "i", "u", "font", "big", "small", "sub", "sup", "h1", "h2", "h3", "h4", "h5", "h6", "cite", "code", "em", "s", "strike", "strong", "tt", "var", "div", "center", "blockquote", "ol", "ul", "dl", "table", "caption", "pre", "ruby", "rt" , "rb" , "rp" ); $htmlsingle = array( "br", "p", "hr", "li", "dt", "dd" ); $htmlnest = array( # Tags that can be nested--?? "table", "tr", "td", "th", "div", "blockquote", "ol", "ul", "dl", "font", "big", "small", "sub", "sup" ); $tabletags = array( # Can only appear inside table "td", "th", "tr" ); $htmlsingle = array_merge( $tabletags, $htmlsingle ); $htmlelements = array_merge( $htmlsingle, $htmlpairs ); $htmlattrs = array( # Allowed attributes--no scripting, etc. "title", "align", "lang", "dir", "width", "height", "bgcolor", "clear", /* BR */ "noshade", /* HR */ "cite", /* BLOCKQUOTE, Q */ "size", "face", "color", /* FONT */ "type", "start", "value", "compact", /* For various lists, mostly deprecated but safe */ "summary", "width", "border", "frame", "rules", "cellspacing", "cellpadding", "valign", "char", "charoff", "colgroup", "col", "span", "abbr", "axis", "headers", "scope", "rowspan", "colspan", /* Tables */ "id", "class", "name", "style" /* For CSS */ );
E.g., element "a" is not allowed, and the wikitext
<a href="meta.wikimedia.org/wiki/Main_Page">Main Page</a>
produces the HTML code
<a href="meta.wikimedia.org/wiki/Main_Page">Main Page</a>
which renders as the wikitext, not working as a link.
Span
Span is also not allowed now, but for Wikipedia this is being discussed, see w:Wikipedia:Span tags poll.
The replacement <div style="display:inline"> can be used, but, oddly, apparently only in a list:
*a <div style="display:inline; color:red">red </div> word #a <div style="display:inline; color:red">red </div> word a <div style="display:inline; color:red">red </div> word
gives
- a redword
- a redword
Outside a list "display:inline" is effectively disabled: the code is retained, but with closure of the paragraph before the styled part and starting a new one after it.
Note that the blank spaces at the end of and just after the styled part are removed; use at the end:
*a <div style="display:inline; color:red">red </div>word
gives
- a redword
Font
For some attributes, like color, one can also use
a <font style="color: red">red</font> word
or
a <font color=red>red</font> word.
giving
a red word
a red word
The font element can even be used to replace span, e.g.
a height of 20000 <font title="30.48 cm" class="title">ft</font> above sea level
giving
a height of 20000 ft above sea level
(note the hover box over "ft").
Use a css line like
.title {color: red; }
to see which text has a hover box.
Div
E.g. to assign the class "red" to a text one can put
<div class="red">example text</div>which gives
.red {color:red}
is applicable.
This is suitable if the color is specifically intended to be red; if it is just for emphasis a more general term for the class would be more appropriate, because css allows the user to choose another method of emphasis (another color, bold, enlarged, etc.).
Note that many readers will not have their own css, specially adapted for such usage, so one cannot refer to "the red text above", etc.
