Introduction

Each table lists support status information for grouped CSS features across recent versions of Internet Explorer. In each section, the first table represents features introduced in CSS 2.1 or earlier, and the second table represents features planned (by the World Wide Web Consortium (W3C)) for CSS 3.

A value of "Yes" in a cell indicates that that feature is implemented in that version of Internet Explorer.

A value of "Partial" in a cell indicates that that feature is only partially implemented in that version of Internet Explorer. For more information, click the link to view that feature's reference page on MSDN.

A value of "No" in a cell indicates that that feature is not implemented in that version of Internet Explorer.
