The 40FINGERS Style Helper Skin object allows you to manipulate the CSS, Javascript links and meta tags DNN loads by default.
You can remove them, change them and add your own.

The StyleHelper also allows you to do this only when certain conditions are met.
Some examples of the available conditions are: browser type / version, username, role, query string etc.
These filters can be positive (include) or negative (exclude).
