Attributes

class

This attribute allows you to designate an element to be a member of a given class. Multiple elements can be assigned to the same class (eg.

class="foo"> ...

class="foo"> ...

), as well as a single element belonging to multiple classes (eg.

class="foo bar"> ...

).

code

codebase[

dir

With this attribute you can define which direction the text is written for a given element, either ltr for left-to-right or rtl for right-to-left.

height

Setting this attribute with a numerical value defines the height of an element in pixels (eg.

height="150"> ...

)

id

This attribute allows you to define a unique identifier for each element. This would be useful for hyperlinks that link to a specific section of a page or when styling using a style sheet.

lang

With this attribute you can specify a language that is used for an element.

style

This attribute allows you to apply specific styling to a given element.

More attributes

accesskey

The accesskey attribute defines a keyboard shortcut for a hyperlink or form element. The combination of keys need to activate the shortcut varies from browser to browser. In Microsoft Internet Explorer the user must press Alt accesskey. If the shortcut is for a link the user must then press Enter to follow the link. The choice of Alt accesskey means that access keys can clash with shortcuts built-in to the browser.

It is quite common to use numbers for the access keys since these don't clash with any major browser's built-in shortcuts, e. g.

  • 1 = Home Page
  • 0 = List of access keys on this website.

There is no standard way to let users know the access keys that are available on the page. Some suggestions can be found in Accesskeys: Unlocking Hidden Navigation.
