style.css is missing!

Ok I found some solution if anybody is interested in it.

Now it is clear for me that there is no “normal” style.css, but some less files and variables php, and the css will be rendered on the go. I do not understand how this system works exactly (they use some twitter bootstrap files what are faaaar from my knowledge).

So I catched the rendered css file with chrome pendule plugin, made it clear with https://cssbeautify.com/ and voila! Now I have the selectors, classes and so on to change the style.

I am sure that there is an easier more straightword solution with less files, but for me as a beginner it is good enough.

Anyway I do not give up and try to understand these less syntax and the rendering procedure.
