s not necessary. With some fixes

Update: Many individuals have composed in or commented on other websites that they think Microsoft is still serving diverse variations of its homepage to different browsers since of variances in header/footer designs,Office Standard 2007 Product Key, or hovers not functioning from the left-side navigation in non-IE browsers.
As far as I can notify,Office 2007 Enterprise Key, I even now only see a single model of both the HTML and CSS currently being served to all browsers. The header and footer use a proprietary gradient transformation to produce the blue-to-white gradients that fails in non-IE browsers:
filter:progid:DXImageTransform.Microsoft.Gradient( )
And every single of the left-side navigation hyperlinks are designed by badly-nested HTML:

Windows

… which IE/Win doesn’t care about,Office Home And Business 2010, so the hover properties work there. But all other browsers correctly recognize the illegal nesting,Office Home And Student 2010 Product Key, and seem to cancel out any hover or active link states.
So,Microsoft Office 2010 Standard Key, still only 1 edition getting served. That’s good. It’s just that this a single version is behaving differently in each and every browser. That’s not necessary. With some fixes, the page could render much more consistently in every modern browser (including IE5.0/Win).
