podamibe widget not responsive

Hi
I noticed when I looked at my site on a tablet, your footer widgets are not calculating screen size, and just dividing the number of footer widgets/2 and putting them two up top, and two at the bottom in the footer area, left jsutified. There is a massive blank area to the left that could be used for one of the widgets and the third could be evenly centred below. Another idea would be on when switching from PC to mobile devices would be to roll up the footer elements into a hamburger menu. So anyway, as a work around, how do I make your footer widgets responsive?
