Responsive Space-Tourism site

What are you most proud of, and what would you do differently next time?

The layout was so hard to implement for all screen sizes. At least for me :P

I feel the css could be simplified, I did some repetitive code defining the grid-areas for the pages, and things related to that.

I just learned how creative utility classes can be, I'm very bad at it but did my first steps

What challenges did you encounter, and how did you overcome them?

Managing the css, somewhat modularized it with sass partials, but it's far from perfect
