Project Description:
This is a very simple project for anyone who knows what they are doing and should not take more than hour at most.

The front page of my site [url removed, login to view] is using html5 mark-up, I am trying to use modernizr ([url removed, login to view]) to make the site backward compatible with older browsers such as IE7 & IE8 that do not support html5 browsers but it does not seem to be working.

All I need is someone with the experience to implement the right script (if necessary) to make the site backward/cross-browser compatible.
It must support all the most commonly used browsers along with the different browser versions.

Please do not bid ridiculous amounts of money for this project as I am aware of the kind of prices pages cost to design.
