I’m guessing you are still working on this cause I had to uncomment your content to be able to see it all, but so far looks really good! I suggest changing the padding on your body section, so that instead of using padding to create space give your body section a set width instead, then a max-width of 100% so that its viewable on mobile… Right now, with 25% padding on each side, on smaller screens, yoru content can only take up 50% of the space.
Also, in your header consider removing the xs col size so that when it scaled down, the blurb will slide under her photo instead of them squishing together. You dont need to list all the col sizes btw, you can just select the smallest one you want to set it for. xs by default means nothing will shift and will always stay in one row, which is why I suggest removing it.
Really cool person to do your Tribute on btw!
