joomla gantry footer-position is off

[Style]

I am using Joomla 3 and Gantry framework to make a site. I just noticed that sometime during my fiddeling with the css f?r the site I have managed to mess up the positioning of the footer. It wont show at the bottom of the page anymore, it just sits fixed under the last module.Can anyone give me a hint of what might be wrong?the site is:http://solstack.infinito.se/homepage
