Is it possible to shift the right sidebar to left?
learning css, and how to use a dom inspector will really help with these questions.
grep is your friend.
I tried that (CSS = Float: left; & Float: right; ), but unfortunately this gives other issues, for example not to be able to press anything in the mobile bootstrap view... so check mobile also...
For bootstrap you'd probably want to use the css styles 'push-xxx' or 'pull-xxx' See getbootstrap.com/css/#grid-column-ordering
