Using a UserContentManager user CSS style sheets can be set to be injected in the web pages loaded by a WebView, by add_style_sheet.

To use a UserContentManager, it must be created using UserContentManager, and then used to construct a WebView. User style sheets can be created with UserStyleSheet.

User style sheets can be added and removed at any time, but they will affect the web pages loaded afterwards.
