The design is pretty basic, but has got some tricky features. I've focused on getting the HTML and BEM-naming straight. I started out using CSS Grid for fun, but ended up refactoring it to Flexbox, because resizing and positioning the staggered items was just easier like that.
This was probably the last time I've done desktop-first.
I am wondering if the way I put the background images in there is the way to go.
