Here I have three main problems when I open my test website using Internet Explorer:
1. The opacity of sidebar in I.E is different in firefox;
2. The sub-menu in products, designers tab won't show up in I.E.;
3. There is a dark grey area in the top and under the "social media" of the sidebar.
Here is my test website: http://188.8.131.52/
Can all these be fixed like the way shown in firefox?
