I'm using the oxygen theme for my site http://www.eiwitshakerecepten.nl
It's a lovely theme but I would like to change something on mobile: on mobile the order of the elements is like this: Header, Menu, Left Side bar, Content, Right Side bar, Footer.
I don't like that the Left Side Bar comes before the content, so I would like to remove the left side bar when I view the site on mobile.
Is this possible? How can I change this easily?
If this is too hard to code, is it maybe possible to make the site unresponsive?
