I have created a somewhat responsive bootstrap layout using the grid system however I wanted to know whether there was a way the column could disappear completely when the screen gets below a certain number of pixels. As you can see from the html, when the screen gets below 767px the side columns go to 1 and the main column goes to 10, but is there a way these side columns can just disappear and the main column can fill up the whole screen?
