Set CSS file globally/ CWD for CSS Files

[sashberd]

1. Is there is a way to set some CSS files globally to whole application?. E.g. Bootstrap.min.css for all views and pages.

2. Next question is there is a way to set up CWD for CSS files. E.g. I have to mention '../css/...' path in all arrays. Defining CWD via provider is a good feature.
