SCSS Huddle Landing with alternate sections

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

I'm proud of having managed to make it work somehow, but frankly it took me too much time and I'm not entirely satisfied with measurements.

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

The grids on the footer part gave me a lot of problems, then through careful testing I discovered it was due to an improper grid area assignment to all images while I wanted to assign it to one image only.

What specific areas of your project would you like help with?

I need advices to keep code more compact and to have consistent measures. Thank you.
