# Add this to CSS:
# .icon { padding-left: 20px; background-repeat: no-repeat;}
#
# use at least 20px line-height for best experiences

# Upload them to your MEDIA_URL's icons subdirectory.

# Template usage:
# {% load icons %}
#
# <a href="/login/" {% icon 'door_in' %}>Login</a>
# <h2 {% icon 'user' %}>{{ user.username }}</h2>
# <p>Please subscribe to our <span {% icon 'feed' %}>RSS feed</span>.</p>
