HtmlStylesheetLoadEventArgs 类

Invoked when a stylesheet is about to be loaded by file path or URL in 'link' element.
Allows to overwrite the loaded stylesheet by providing the stylesheet data manually, or different source (file or URL) to load from.
Example: The stylesheet 'href' can be non-valid URI string that is interpreted in the overwrite delegate by custom logic to pre-loaded stylesheet object
If no alternative data is provided the original source will be used.
