Landing page using Flexbox

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

Finally could use some grid and found the experience quite pleasant. Wasn't so sure about working with markers and styling h elements.

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

Couldn't understand the margins while styling lists, but by combining some of properties i was able to get the result that satisfied me

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

I would really want to get rid of HorizontalLine div as i'm not happy with that solution, other than that i'd just like to hear any feedback
