<input> elements of type button are rendered as simple push buttons, which can be programmed to control custom functionality anywhere on a webpage as required when assigned an event handler function (typically for the click event).
elements have no default behavior (their cousins, and are used to submit and reset forms, respectively). To make buttons do anything, you have to write JavaScript code to do the work.
Buttons are for triggering actions. When do you use the element? A good rule is to use a button when there is “no meaningful href.” Here’s another way to think of that: if clicking it doesn’t do anything without JavaScript, it should be a .
A that is within a , by default, will submit that form. But aside from that, button elements don’t have any default behavior, and you’ll be wiring up that interactivity with JavaScript.
