You need to place all the text and images to be displayed between the <BUTTON> and </BUTTON>. The size of the button will automatically adapt itself to suit the content.
The <BUTTON> tag has a TYPE attribute that indicates the action you want to associate with the button. It can take the following values:
submit: validates the form and executes the action defined by the ACTION attribute of the <FORM> tag.
reset: resets all controls to their initial default values.
button: no particular action is associated with the button.
The button can reference a particular JavaScript function through the onClick attribute.
