Upfront: Images and text full width

Hello!

I'm looking accomplish something similar to what this website (https://www.realthread.com) has done but I'm not sure how to build it using Upfront. I attached a image of the area of the page I'm interested in. I like how the image expands based on the size of the page and the text is on the side.

Any ideas on the best way to accomplish?

Thanks!
