Using boostrap.css file in Rails production/heroku w/o LESS or SASS

Question

I\'m trying to use the glyphicons provided by bootstrap in my rails 4.0beta1 app. Everything works fine in development, but in production nothing gets rendered, and in the herok

Answer 1

Well, oddly, background-image did not seem to work in production. I was loading other background images using just the background: property, so I tried that and now it (magically) works in production:

background: url(<%= asset_path 'glyphicons-halflings.png' %>);

with bootstrap.css.erb as the filename.

Still confused as to why background-image was working in development but not production ...
