Help: Leaving a Grid Blank, et al

Hi! I’m new to webflow.

First, I want to know if I can leave some areas of a grid layout blank because I’m planning to maximize the white space of my website. I tried doing it already but realized that has a negative impact in terms of mobile responsive. If you’re going to preview my site (link below), you would notice how I want to lay out my site contents. I also want to stick with this kind of layout since it’s a case study for my portfolio.


Second, I want to know if it’s possible to make a sticky element temporary. As you can see in the screenshot provided, I want the “Consumer Needs” text to be the sticky element. The texts on the right will continue to be scrolled. I would also like this sticky element to return back to its normal state or disappear once everything the “Consumer Needs” section has been read.

I’m open to any suggestions.

Thanks!
