Is it possible to update a CSS file from Python

[ndc85430]

css is just a text file!.

While this is true, the structure of it does have meaning. It would be better to use a library because

- it saves you having to write and maintain code that is likely not the thing you want to care about when writing your application,
- since a library is focused on a particular task, they'll do a better job than something hand rolled (better tested, catches errors, etc.),
