CSS Type

Give the actual CSS for a Stylesheet
A CSS Property is a large text block, which must contain only CSS. If you don't know CSS, you probably don't want to worry about this Type -- suffice it to say, it is the standard Web programming language for managing the fine details of the look and feel of a Webpage.
IMPORTANT: the CSS Property only matters on a Stylesheet! You fill in the CSS for a Stylesheet, and then point your Instances, Models or Space to that Stylesheet in order to use it. Adding the CSS Property to anything other than a Stylesheet doesn't so anything.
Note that we plan to begin white-listing CSS constructs in the near future. In the medium term, we expect to allow nearly all of CSS, but it will be with certain constraints on what you can apply the CSS to, and some constructs will be forbidden. Do not assume that absolutely all of CSS is legal to use! If you need a specific CSS construct, and aren't sure whether it will be legal, please ask.
