### Function

# WebKit2 UserStyleSheetnew

#### Declaration [src]

    WebKitUserStyleSheet*
    webkit_user_style_sheet_new (
      const gchar* source,
      WebKitUserContentInjectedFrames injected_frames,
      WebKitUserStyleLevel level,
      const gchar* const* allow_list,
      const gchar* const* block_list
    )

#### Description [src]

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 `NULL` 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.

Available since: | 2.6
