Material Design Lite, for Rails!

A gemified version of Google's Material Design Lite library.


To your Rails application's Gemfile, add

gem 'material_design_lite-rails', '~> 1.3'

And then run

$ bundle


To your application.js file, add:

  //= require material


Do one of the following:

To your application.css , add

  *= require material


If you're using sass, use sass's @import in your application.scss.

  @import "material";

This gem only provides the compiled CSS file from google/material-design-lite.

If you're looking for the individual Sass files, so you can take only parts of Material Design Lite, you should use the rubysamurai/material_design_lite-sass gem instead.


Material Design Lite uses a font called 'Material Icons'. You can either load this font from google, or host it yourself.

Load font from google

Add the following line to your application.html.erb view layout file, in the <head> section:

  <%= stylesheet_link_tag "https://fonts.googleapis.com/icon?family=Material+Icons" %>


Host font locally

Use the material_icons gem to host the font locally.


This gem is versioned semantically, in line with google/material-design-lite

If there needs to be a release of this gem without a corresponding release to google/material-design-lite' to the repo, an additional digit will be added (so if this gem's version is, google's version would still be 1.0.0).

The first three digits will always be the same as google/material-design-lite.


  • Add tests (make sure CSS/JS loads, and check version)
  • Add view helpers, to ease burden of manually adding all the classes.
  • Fix issue where you need to manually create node_modules directory
