Q: How did you make the top buttons move like that and why doesn't it work in IE7 or 8?
A: The effect we used for the top buttons is pure CSS, but it is CSS3 which is not supported by IE7 or 8. At the top of the base.css file we commented the section that has this code. We used two classes. .transfrom and .imgwrapper. These affect the top buttons because we wrapped them in the imgwrapper div and added the transfrom img class, like this:
<div class="imgwrapper"><img class="transform" style="float: right;" src="/images/v_button.png" alt="Volunteer" width="125" height="112" /></div>
