You can create a clickable button on a web page with Cascading Style Sheets (CSS) as explained in Creating a button with CSS or simply use the HTML button tag, i.e. <button>label_for_button</button>. You can apply a style attribute to the button to change the background color on the button, display attributes for the text, such as bold, etc. and can specify an action that will be taken if someone clicks on the button. The button tag has been part of HTML since version 4.0.
