Huddle-- Responsive Landing Page | Mobile First

Finally, I submitted my first solution, but I still feel awkward about certain decisions I made in the design. So any criticism, insights, and suggestions are much appreciated.

The things I felt awkward about: Using vh for top and bottom margins. Center the container based on the current viewport. Not having used the grid from the start.

So my idea was to center the container with a flex layout so that the container is at the center no matter the screen size. However, I'm uncertain if this is good or bad practice and if I should try to avoid this in future projects.

Again, any suggestions and criticism are appreciated.
