drg_material_icons provides the Material-icons web fonts and stylesheets as a Rails engine for use with the asset pipeline.

drg_material_icons gem also provides compatibility with the old font-awesome-rails gem. If you are still using old Font awesome v4.7 icons and want to upgrade to more rich Google material icons you simply replace font-awesome-rails gem with drg_material_icons gem.


Add this code to your Gemfile:

gem "drg_material_icons"

and run bundle install.


In your application.css, include the css file:

 *= require drg_material_icons

Then restart your webserver if it was previously running.

If you are user of DRG CMS you don't need to do anything. Code is included with drg_cms gem.


drg_material_fonts gem also provides some helpers (mi_icon and mi_stacked_icon) that will help you include icons into your code.

mi_icon "photo_camera"
# => <i class="mi mi-photo_camera"></i>

mi_icon "photo_camera", text: "Take a photo"
# => <i class="mi mi-photo_camera"></i> Take a photo

mi_icon "chevron_right", text: "Get started", right: true
# => Get started <i class="mi mi-chevron_right mi-poll-right"></i>

(:li, mi_icon("check li", text: "Bulleted list item"))
# => <li><i class="mi mi-check mi-li"></i> Bulleted list item</li>

drg_material_icons includes two material icon font types. Regular and outline. To get outline type of icons simply add -o suffix to icon name.

mi_icon "photo_camera-o"
# => <i class="mi-o mi-photo_camera"></i>

mi_icon "photo_camera-o", text: "Get started"
# => Get started <i class="mi-o mi-photo_camera">Get started</i>

Support for spinning icons.

mi_icon "settings-o spin"
# => <i class="mi-o mi-settings mi-spin"></i>

There is also support for colored icons.

mi_icon "photo_camera red"
# => <i class="mi mi-camera_retro mi-red"></i>
# other build in options are green,blue,violet

Adding your own CSS keywords is as simple as adding them to your CSS files.

.mi-yellow {color: yellow}

and use them in your application.

mi_icon "photo_camera yellow"
# => <i class="mi mi-camera_retro mi-yellow"></i>

Compatibility with font-awesome-rails gem

drg_material_icons gem is a fork of font-awesome-rails gem and is its 100% replacement. It includes fa_icon method as an alias to mi_icon method, which is just tad updated from original font-awesome-rails project. Therefore, you can mix use of old and new variant of method call.

mi_icon "photo_camera"
# => <i class="mi mi-photo_camera"></i>

# or

fa_icon "photo-camera"
# => <i class="mi mi-photo_camera"></i>

Some of Material icons names are the same as FontAwesome icons, but most are not and you get blank space instead of icon image. There are two solutions to this problem. You can find font icon replacement on https://fonts.google.com/icon and update icon name in your source code, or define CSS code for the icon name in your CSS files.

.mi-times:before {content: '\e5cd'}
