HTML and CSS Reference
In-Depth Information
The <button> control provides for a greater variety and richer contents
than its <input> analogs. Everything between the <button> and </button>
tags becomes the content of the button, including any acceptable body
content, such as text or multimedia. For instance, you could include an
image and related text within a button, creating attractive labeled icons
in your buttons. The only verboten element is an image map because its
mouse- and keyboard-sensitive actions interfere with the form button.
9.6.2. The type Attribute
Use the type attribute for the <button> tag to define the button's action.
You should set its value to submit , reset , or button . Like its <input>
analog, a <button type=submit> form element, when selected by the
user, tells the browser to package and send the contents of the form
to the forms-processing server or email it to the mailto recipient. Using
type=reset creates a conventional reset button, and using type=button
creates a conventional push button.
For example, Figure 9-5 shows the following exclaim.gif icon inset on a
3D button that pushes in and pops back out when the user clicks it with
the mouse. In doing so, the browser submits the form to the server:
