Button Types
There are three types of buttons:
submit — Submits the current form data. (This is default.)
reset — Resets data in the current form.
button — Just a button. Its effects must be controlled by something else
(that is, with JavaScript).
It used to be the case that buttons primarily appeared in the context of forms,
where the default submit behavior made perfect sense. Today, it is common to see buttons
in all sorts of in-browser app contexts, and so it isn’t always clear at first glance at
the markup. Therefore, it is a good practice to always declare the type of a button
explicitly.
Difference between <button type="submit"> and <input type="submit">
Both <button type="submit"> and <input type="submit"> display as buttons and cause the form data to be submitted to the server.
The difference is that <button> can have content, whereas <input> cannot (it is a null element). While the button-text of an <input> can be specified, you cannot add markup to the text or insert a picture. So <button> has a wider array of display options.
There are some problems with <button> on older, non-standard browsers (such as Internet Explorer 6), but the vast majority of users today will not encounter them.
