Property values

Type: BSTR


Standards-compliant mode is not switched on.


Standards-compliant mode is switched on.


When standards-compliant mode is switched on (also called "strict mode"), Windows Internet Explorer displays the document according to the World Wide Web Consortium (W3C) Cascading Style Sheets (CSS) standard. When standards-compliant mode is not switched on (also called "quirks mode"), the document is displayed as it was displayed in previous versions of Internet Explorer.

The IHTMLDocument5::compatMode property is deprecated in Windows Internet Explorer 8 in favor of the IHTMLDocument6::documentMode property.

With Microsoft Internet Explorer 6 and later, you switch on standards-compliant mode by including the !DOCTYPE declaration at the top of your document, specifying a valid !DOCTYPE in the declaration, and in some cases, specifying the !DOCTYPE or !DOCTYPE. The !DOCTYPE element specifies the unique name of the Document Type Definition (DTD), and can be appended with the version number of the DTD. The !DOCTYPE element specifies the definition of the DTD that is specified in the !DOCTYPE. The !DOCTYPE element specifies the location of the DTD.
