Menu body moves to the left



When I click the menu icon, it looks as if the body slides to the right. But the lessons continually say that it is pushing to the left.
Am I missing something?


I think I understand it now. It looks as if it's pushing the body 285px FROM the left, as opposed to 285px to the left. Kind of like setting a left margin of 285px pushing the content farther from the left.
I hope this is correct.


Yes, very good. It will offset body by 285px from the left side, i wrote an answer about position/margin/left, you can find it here, hope it helps


Thank you so much for the help!
