HTML class Attribute


HTML Standard Attributes Reference HTML Standard Attributes

Definition and Usage

The class attribute specifies a subtype for the element.

The class attribute is mostly used with CSS to style elements. It can also be used with JavaScript (using the HTML DOM) to change the HTML element with the specified class.

It is possible to assign multiple classes to an element by using space as a separator in the class attribute. This allows you to combine several CSS styles for an element.

Syntax

<element class="class">Some text or element</element>
OR
<element class="class" />

Parameter Description
class Required. The class/subtype of the element.

Naming rules:

  • Must begin with a letter (A-Z or a-z) or number (0-9)
  • Can be followed by: letters (A-Za-z), digits (0-9), hyphens ("-"), underscores ("_"), colons (":"), and periods (".")
element Required. The HTML element using the class.

The class attribute can be used on almost all HTML elements.

Exceptions:

  • base
  • head
  • html
  • meta
  • param
  • script
  • style
  • title

WAPT is able to generate up to 3000 simultaneously acting virtual users using standard hardware configuration. Virtual users in each profile are fully customizable. Basic and NTLM authentication methods are supported. Graphs and reports are shown in real-time at different levels of detail, thus helping to manage the testing process.
