DocumentType.remove()

The DocumentType.remove() method removes a document's doctype.

Note: Removing the document's doctype will set the rendering mode to quirks mode! Please don't do this. Willfully designing for quirks mode is not going to help you. If you need to work around issues with old Internet Explorer browsers, you might want to look into using conditional comments, or other workarounds.
