1.3 Microsoft Implementations

The following Microsoft products implement some portion of [W3C-PNG]:

  • Windows Internet Explorer 7

  • Windows Internet Explorer 8

In addition, each version of Windows Internet Explorer implements multiple document modes, which can vary individually in their support of the standard. The following table lists the document modes available in each version of Internet Explorer:

Browser Version

Document Modes Supported

Internet Explorer 7

Quirks mode

Standards mode

Internet Explorer 8

Quirks mode

IE7 mode

IE8 mode

Throughout this document, the document mode appears first followed by the browser version in parentheses. Only those document modes and versions of Internet Explorer for which there is a variation note will be listed. If the document mode is not listed, conformance to the specification can be assumed.

Note   "Standards mode" in Internet Explorer 7 and "IE7 mode" in Internet Explorer 8 refer to the same document mode. "IE7 mode" is the preferred way of referring to this document mode across all versions of the browser.
