# HTML <button> tag

## Example

A button is marked up as follows:

<button type="button">Click Me!</button>

Try it yourself!

## Definition and Usage

The <button> tag defines a push button.

Inside a button element you can put content, like text or images. This is the difference between this element and buttons created with the input element.

Always specify the type attribute for the button. The default type for Internet Explorer is "button", while in other browsers (and the W3C specification) it is "submit".

## Browser Support

The <button> tag is supported in all major browsers.

Important: If you use the button element in an HTML form, different browsers will submit different values. Internet Explorer will submit the text between the <button> and </button> tags, while other browsers will submit the content of the value attribute. Use the input element to create buttons in an HTML form.
