About Web browser support for Web Part Pages

Web browser support for Web Part Pages can be categorized into 3 levels:

Level 1 support is the highest level of visual and functional support. Browsers that provide level 1 support include Microsoft Internet Explorer 5.5 and later for Microsoft Windows.
At level 2 support, a few visual and functional features are not available to some browsers, and some other features are compromised and behave differently than in level 1 browsers. However, the majority of features are still available to users. Browsers that provide level 2 support include Microsoft Internet Explorer 5.01 SP3 for Windows and Netscape Navigator 6.2 and above for Windows.
Level 3 support allows users to access the data they need, with an acceptable though not necessarily optimal user experience. These browsers behave with minor differences across operating systems, and such differences are not always addressed with alternate support. Browsers that provide level 3 support include Microsoft Internet Explorer 5.2 for Macintosh and Netscape Navigator 6.2 for Macintosh and Unix.
