CSS fix needed so our site works in Internet Explorer 7-

The navigation buttons on our site, [login to view URL], work properly on Chrome, Opera, Firefox and Internet Explorer 8 when it's working at standards mode. When earlier versions of Internet Exlporer are used, or if IE8 is set to non-standard mode, the navigation buttons appear as a set of steps rather than in a horizontal line. If you can provide an elegant fix for this small part of the site that will work in IE7, IE8 (and ideally IE6 but we accept that may be too much to ask), without breaking the functionality of any other part of the site, and retaining full compatibility with other popular standards-based browsers on all platforms, please bid for this job. Please visit [login to view URL] using a variety of browsers so you can experience the problem that we are trying to describe here. This job concerns the 'hello' 'sign up' 'your site' navigation bar. We think that this is a style sheet issue primarily, but since the buttons also call javascript it may be worth bidding on this project only if you have skills in both. The html, css and relevant javascript files are available. Best wishes The Team at helpfulwebhosting
