Material Design Lite

An implementation of Material Design components in vanilla CSS, JS, and HTML

Material Design Lite (MDL) lets you add a Material Design look and feel to your static content websites. It doesn't rely on any JavaScript frameworks or libraries. Optimized for cross-device use, gracefully degrades in older browsers, and offers an experience that is accessible from the get-go.

Use MDL on your site?

This document is targeted at developers that will contribute to or compile MDL. If you are looking to use MDL on your website or web app please head to getmdl.io.

Browser Support

IE9 IE10 IE11 Chrome Opera Firefox Safari Chrome (Android) Mobile Safari
B A A A A A A A A

A-grade browsers are fully supported. B-grade browsers will gracefully degrade to our CSS-only experience.

Getting Started

Download / Clone

Clone the repo using Git:

git clone https://github.com/google/material-design-lite.git

Alternatively you can download this repository.

Windows users, if you have trouble compiling due to line endings then make sure you configure git to checkout the repository with lf (unix) line endings. This can be achieved by setting core.eol.

git config core.eol lf
git config core.autocrlf input
git rm --cached -r .
git reset --hard

Remember, the master branch is considered unstable. Do not use this in production. Use a tagged state of the repository, npm, or bower for stability!

What's included

In the repo you'll find the following directories and files.

File/Folder Provides
CONTRIBUTING.md MDL contribution guidelines.
docs Files for the documentation site.
gulpfile.js gulp configuration for MDL.
LICENSE Project license information.
package.json npm package information.
README.md Details for quickly understanding the project.
src Source code for MDL components.
templates Example templates.
test Project test files.

Build

To get started modifying the components or the docs, first install the necessary dependencies, from the root of the project:

npm install && npm install -g gulp

MDL requires NodeJS 0.12.

Next, run the following one-liner to compile the components and the docs and spawn a local instance of the documentation site:

gulp all && gulp serve

Most changes made to files inside the src or the docs directory will cause the page to reload. This page can also be loaded up on physical devices thanks to BrowserSync.

To build a production version of the components, run:

gulp

This will clean the dist folder and rebuild the assets for serving.

Templates

The templates/ subdirectory contains a few exemplary usages of MDL. Templates have their own, quasi-separate gulp pipeline and can be compiled with gulp templates. The templates use the vanilla MDL JS and themed CSS files. Extraneous styles are kept in a separate CSS file. Use gulp serve to take a look at the templates:

Templates are not officially supported in IE9 and legacy browsers that do not pass the minimum-requirements defined in our cutting-the-mustard test.

The templates refer to CDN hosted versions of the libraries. If you'd like to test the templates against locally built MDL libraries you need to run the templates:localtestingoverride gulp task before running gulp serve:

gulp all && gulp templates:localtestingoverride && gulp serve

Beware as any changes to the templates directory will automatically revert the templates local testing overrides. In this case make sure you run the templates:localtestingoverride gulp task again or modify the watch() function in the gulp file.

Versioning

For transparency into our release cycle and in striving to maintain backward compatibility, Material Design Lite is maintained under the Semantic Versioning guidelines. Sometimes we screw up, but we'll adhere to those rules whenever possible.

Feature requests

If you find MDL doesn't contain a particular component you think would be useful, please check the issue tracker in case work has already started on it. If not, you can request a new component. Please keep in mind that one of the goals of MDL is to adhere to the Material Design specs and therefore some requests might not be within the scope of this project.

Want to contribute?

If you found a bug, have any questions or want to contribute. Follow our guidelines, and help improve the Material Design Lite. For more information visit our wiki.

Do you include any features that a framework comes with?

Material Design Lite is focused on delivering a vanilla CSS/JS/HTML library of components. We are not a framework. If you are building a single-page app and require features like two-way data-binding, templating, CSS scoping and so forth, we recommend trying out the excellent Polymer project.
