I tried to use an online unminifier (http://mrcoles.com/blog/css-unminify/). I replaced the minimized with the unminized text. Afterwards I called the URL, the whole website was not layouted.
But I really need to configure some css-classes, just integrating a new css-lib would not help.
What did I wrong? Maybe the unminifier does not work and you can recommend me a better one?
I've always used this one and it's always worked for me :)
