Alignment issues and Responsiveness not working


I am following this webflow tutorial by webflow school Make your homepage fully responsive — Build a custom portfolio in Webflow, Day 6 - YouTube

I am trying in introduce breakpoints to my design. However when I increase the size to 1920, my banner image does not become responsive. I am not sure how to fix this.

Another problem I am facing is that the spacing on the sides of the section where I have my projects is unequal and the section is not in the centre. I don’t know how to fix this.

The primary device I am using to design is a 14" macbook pro M1 pro

I have attached the link to my web flow site below
