Is it possible to change the width if the off-canvas menu? In my designs the off-canvas menu is the left column on a large screen. On mobile devices it is 'off-canvas' on the left. In Both cases it is too wide. I need it to be about 2/3rds if the default width. Just ends up with a lot of wasted space.
I'm not doing SaSS. Haven't learned it. Don't really need it for any other purpose.
Can I set the width of the OC menu with CSS or some other simple way?
