HTML

html

The root element that specifies that the content of the document is HTML. The opening tag immediately follows the DOCTYPE declaration and the closing tag is the last thing in the document. The html element must contain the headand the body elements.

Attributes

xmlns is used to define the XML namespace. The value must be http://www.w3.org/1999/xhtml.

Example

<html xmlns="http://www.w3.org/1999/xhtml" xml:lang="en">

<head>

[stuff]

</head>

<body>

[stuff]

</body>

</html>

FIELDSET

fieldset

Defines a group of related form items.

Example

<fieldset>

<div>First name: <input /></div>

<div>Surname: <input /></div>

</fieldset>

DT

Definition term. Used in conjunction with dl to define a definition list and dd, to define the description linked with the term.

Example

<dl>

<dt>Dog</dt>

<dd>A carnivorous mammal of the family Canidae.</dd>

</dl>

EM

Emphasis.

Example

<p>That's <em>emphasis</em> ladies and gentlemen.</p>

DOCTYPE

DOCTYPE

Document type declaration. This is used to let the browser know what version of HTML you are using. If you don't use it, or if you get it wrong, the browser will assume you don't know what you're doing and switch to 'quirks mode', which will not render things as they should be. Apparently it's more 'forgiving' but it actually seems to be quite random and confusing.

The case must be like that in the example below (with upper case 'DOCTYPE'). It does not close like other tags.

Example

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Strict//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-strict.dtd">
