oakbow / application_helper.rb
Last active December 28, 2015 00:18
for using icons easily, i add helper methods in application_helper.rb. I made this for icomoon, but i think you may be able to use this with Font-Awesome, Twitter Bootstrap2.0 (not WebFont but png icons) and Bootstrap3.0.
# to make <i> easily.
# name: icon class name.
# data: webfont number.some webfonts like icomoon can use with this.
# color: for Bootstrap2.0. you can set this 'white' for white icon.
# class: you can set css class to <i> tag.
# style: you can set inline css to <i> tag.
