This means that if you want to update or use the value and the displayed content in concert, you would need to use the button input, or else do a lot more scripting to sync the value with its content. With the element, the button displays its content. With the button type input, the value is displayed on the button itself. So, if the element is basically the same, except better, why use the button input type at all? The answer is the value attribute. This means that the element can have a picture, or marked-up text, while the button input cannot have either. The difference is that the element can have content, while the element is null (that is, it does not have a closing tag and cannot contain any content. By default, they are both displayed as buttons, and they both usually rely on JavaScript for their utility - neither one of them has much use in a strict form-input and submission paradigm. In addition to the button type of input, there is a separate element which is functionally very similar. For the most part, the button input is used in conjunction with JavaScript.

The button input type creates an form button, the value of which is displayed as the text or label on the button.
