I am trying to figure out how to use the Raw SCSS section under advanced settings in the Roshni Lite theme to adjust column sizes. Here's the problems:
1. 3 column theme (which I want) but it appears the maximum width is about 1200 pixels. Most users are on 1920 screens or greater these days, so there is SIGNIFICANT whitespace.
2. I'd like the left column to be about 300 pixels, the right about 300 pixels, and the middle to fill in the rest (so 680 pixels on a 1280 display, 1320 on a 1920 display.
How can I make use of the Advanced settings to make these changes? I've attached a picture of the current view with notes so you can visualize what I am trying to do.
I appreciate any help you all can give me on this.
