How to use fonts in Rails 4

Question

I have a Rails 4 application and I am trying to use a custom font.

I have followed many tutorials on this and somehow it\'s just not working for my application.

Answer 1

Your @font-face declaration is very close, you are just missing the /assets prefix within the url declaration.

@font-face {
    font-family: 'HDVPeace';
    src: url('/assets/HDV_Peace.eot');
    src: url('/assets/HDV_Peace.eot?iefix') format('eot'),
         url('/assets/HDV_Peace.woff') format('woff'),
         url('/assets/HDV_Peace.ttf') format('truetype'),
         url('/assets/HDV_Peace.svg#webfont') format('svg');
}

Anything that has been added to assets.paths is available directly under the /assets path in both development and production. You only need the asset path modification line within application.rb, doing it again in development.rb and production.rb is just redundant.

Additionally, all of the font formats are essentially binary. There is no need to pre-compile them, so you can safely remove the assets.precompile addition.

This worked for me on a Rails 4.1 app.

1. Add the fonts under `app/assets/fonts`
2. Call them from a `.css.scss` file as follows:

@font-face {
  font-family: 'icomoon';
  src: url(font-path('icomoon.eot') + "?#iefix") format('embedded-opentype'),
    url(font-path('icomoon.woff')) format('woff'),
    url(font-path('icomoon.ttf'))  format('truetype'),
    url(font-path('icomoon.svg') + "#icomoon") format('svg');
}
[class^="icon-"], [class*=" icon-"] {
  font-family: 'icomoon';
  speak: none;
  font-style: normal;
  font-weight: normal;
  font-variant: normal;
  text-transform: none;
  line-height: 1;
  -webkit-font-smoothing: antialiased;
  -moz-osx-font-smoothing: grayscale;
}

Answer 3

Sometimes fonts are not detected from the assets/fonts directory.

If security is not an issue, we can put the fonts directory into the public folder. They will then be available at a public/ level.

Answer 4

Forget about changing anything in Rails 4 in your application.rb. Just add /assets/ prefix like @Parker Selbert said and the following will work:

@font-face {
  font-family: 'custom-font-name';
  src: font-url('/assets/_folder_/fontX-webfont.eot');
  src: font-url('/assets/_folder_/fontX-webfont.eot?#iefix') format('embedded-opentype'),
       font-url('/assets/_folder_/fontX-webfont.woff') format('woff'),
       font-url('/assets/_folder_/fontX-webfont.ttf') format('truetype'),
       font-url('/assets/_folder_/fontX-webfont.svg#sociconregular') format('svg');
  font-weight: normal;
  font-style: normal;

}

I found this article to solve all of my problems.

Answer 6

Please do not hardcode your font directory since the location is dynamic.

Just like there are built-in helpers for images there is are also built-in helpers for fonts: http://api.rubyonrails.org/classes/ActionView/Helpers/AssetUrlHelper.html#method-i-font_url

Example:

@font-face {
    font-family: 'QuicksandOTF';
    src: font_url('Quicksand-Regular.otf') format('opentype');
    font-weight: normal;
    font-style: normal;
}
