Although the tag has been around W3C for a while, Dreamweaver still creates buttons as "form buttons".
<input type="submit" name="button" id="button" value="Click Me">
The form input button creates generic browser buttons, and can be customized using css. However, an easier way to manage the styling of buttons on your site is to use the "button" tag.
<button type="button">Click Me!</button>
This allows a developer to create and use push buttons outside of FORMS in a manner that is better suited for site styling and flexibility.
