The Material Design Lite (MDL) button component is an enhanced version of the standard HTML <button> element. A button consists of text and/or an image that clearly communicates what action will occur when the user clicks or touches it. The MDL button component provides various types of buttons, and allows you to add both display and click effects.

Buttons are a ubiquitous feature of most user interfaces, regardless of a site's content or function. Their design and use is therefore an important factor in the overall user experience. See the button component's Material Design specifications page for details.

The available button display types are flat (default), raised, fab, mini-fab, and icon; any of these types may be plain (light gray) or colored, and may be initially or programmatically disabled. The fab, mini-fab, and icon button types typically use a small image as their caption rather than text.

Basic use

To use any MDL component, you must include the minified CSS and JavaScript files using standard relative-path references in the <head> section of the page, as described in the MDL Introduction.

To include an MDL button component:

 1. Code a <button> element. Include any desired attributes and values, such as an id or event handler, and add a text caption or image as appropriate.


 2. Add one or more MDL classes, separated by spaces, to the button using the class attribute.

<button class="mdl-button mdl-button--raised">Save</button>

The button component is ready for use.


A button with the "raised" effect.

<button class="mdl-button mdl-button--raised">Save</button>

A button with the "fab" effect.

<button class="mdl-button mdl-button--fab">OK</button>

A button with the "icon" and "colored" effects.

<button class="mdl-button mdl-button--icon mdl-button--colored">?</button>

Configuration options

The MDL CSS classes apply various predefined visual and behavioral enhancements to the button. The table below lists the available classes and their effects.
