A Document Type Declaration, or DOCTYPE, is an instruction that associates a particular SGML or XML document (for example, a webpage) with a Document Type Definition (DTD). Syntax The general syntax for a document type declaration is: <!DOCTYPE root-element PUBLIC "FPI" ["URI"] [ <!-- internal subset declarations --> ]>

Forms aren't the easiest of things to use for people with disabilities. Navigating around a page with written content is one thing, hopping between form fields and inputting information is another. Because of this, it is a good idea to add a number of elements to the form. Labels Each form field should have its own label. The label tag sorts this out, with a for attribute that associates it to a form element:

Quotations blockquote, q and cite are used for quotations. blockquote is block-line and used for large citations, whereas q is in-line and used for smaller phrases. cite is also in-line and preferable to q for its semantic nature and possible future deprecation of q. Again, the title attribute can be used to show where the citation has come from.

abbr and acronym are used for abbreviations and acronyms respectively. An abbreviation is a shortened form of a phrase. Very general. An acronym however is an abbreviation made up of the initial letters (or parts of words) of the phrase it is representing. So CSS is a valid acronym, whereas HTML and XHTML are not (if 'Hypertext markup language' was an acronym, it would be 'HML'. Similarly, XHTML would be EHML).

Definition Lists The dl element gets the ball rolling, similar to the ul and ol elements, establishing the list. Rather than there being an li element though, definition lists have a dt element, which is the definition term, followed by a dd element which is a definition description associated to the dt element. There doesn't have to be one dt followed by one dd, there can be any number of either. For example, if there are a number of words that have the same meaning, there might be a number of dt's followed by one dd. If you have one word that means various different things, there might be one dt followed by several dd's.
