A CSS style sheet which can be injected in loaded pages.

Constructors

class UserStyleSheet
classmethod new(source: str, injected_frames: UserContentInjectedFrames, level: UserStyleLevel, allow_list: Sequence[str] | None = None, block_list: Sequence[str] | None = None) → UserStyleSheet

Creates a new user style sheet.

Style sheets can be applied to some URIs only by passing non-null values for allow_list or block_list. Passing a None allow_list implies that all URIs are on the allow_list. The style sheet is applied if an URI matches the allow_list and not the block_list. URI patterns must be of the form [protocol]://[host]/[path], where the host and path components can contain the wildcard character (*) to represent zero or more other characters.

Added in version 2.6.
