Definition and Usage

The <button> tag defines a clickable button.

Inside a <button> element you can put text (and tags like <i>, <b>, <strong>, <br>, <img>, etc.). That is not possible with a button created with the <input> element!

Tip: Always specify the type attribute for a <button> element, to tell browsers what type of button it is.

Tip: You can easily style buttons with CSS! Look at the examples below or visit our CSS按钮 tutorial.
