Hi, sorry for the delayed response, for some reason I couldn’t answer on mobile.

I was mainly talking about the part where you mentioned the media queries. In case you didn’t know what the <picture> tag is, I found this article to be helpful: https://webdesign.tutsplus.com/tutorials/quick-tip-how-to-use-html5-picture-for-responsive-images--cms-21015

Might be worth adding to your essay, or maybe write a part 2 specifically about the <picture> tag.
