HTML
Inside the button element, you can place content, such as text or images. This is the difference between this element and buttons created using input elements.
The only prohibited element is the image map, as its mouse and keyboard-sensitive actions interfere with the behavior of the form buttons.
Always specify the type attribute for buttons. The default type in Internet Explorer is "button", while the default in other browsers (including the W3C specification) is "submit".
