CSS Compatibility in Internet Explorer

  • Article

With each new release of Windows Internet Explorer, support for the World Wide Web Consortium (W3C) Cascading Style Sheets (CSS) standard has steadily improved. Microsoft Internet Explorer 6 was the first fully Cascading Style Sheets, Level 1 (CSS1)-compliant version of Internet Explorer. Windows Internet Explorer 8 is fully compliant with the Cascading Style Sheets, Level 2 Revision 1 (CSS2.1) specification and supports some features of Cascading Style Sheets, Level 3 (CSS3). Windows Internet Explorer 9 and Internet Explorer 10 add even more support for many CSS3 modules.

Note  It is important to remember that many CSS3 modules are still in the Working Draft or Last Call stages. Until they reach the Candidate Recommendation stage, they could change significantly. For more information, see the latest CSS3 draft modules.

If your website targets browsers that include earlier versions of Internet Explorer, you want to know the level of CSS compliance for those versions. This article provides an at-a-glance look at CSS compliance across recent versions of Internet Explorer, including support in Internet Explorer 9 and Internet Explorer 10.

Note  Newer features will not work on webpages that have an older document compatibility mode specified. For instance, a feature introduced in Internet Explorer 9 will not work if the page has been set to display in IE8 Standards mode, even if you're viewing the page in Internet Explorer 9. For more information on document compatibility modes, see Defining Document Compatibility.

This article's organization is loosely based on that of the CSS reference documentation on MSDN. It contains the following sections:

  • Introduction
  • At-rules
  • Selectors
    • Element Selectors
    • Attribute Selectors
    • Combinators

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 CSS2.1 or earlier, and the second table represents features planned (by the W3C) for CSS3.

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

A value of "Partial" in a cell indicates that the 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 the feature is not implemented in that version of Internet Explorer.

A value of "Updated" in a cell indicates that the feature has been updated in that version of Internet Explorer.
