Sidebar height equal to Main Content area

my problem is that I want to have the color of the #promocion area (where the hands animation show) to be equal in height to my Main content area (Fluid, kinda new here and don't know how to do this).

I try to do a height 100% i开发者_运维技巧n #promocion but doesn't work in IE...

Check out my CSS & website just a sec...

Thank you for your time...

You are looking for the holy grail of layouts. A List Apart will be a great resource for not only the hows but also for the whys.

My favorite method for this is still Faux Columns at A List Apart. Holy Grail seems like overkill here.

There are several ways you can accomplish this. You can do it with some basic Javascript. You can also try the "Faux Columns" approach, although I am not a huge fan of the technique myself.
