Grid video:
The part of the caption that is helpful to me is the part that talks about leaving room to breathe because sometimes it’s hard to know if a certain amount of white space is enough for the composition, it’s an issue that I struggle with more often than not, making it work properly.
Hierarchy video:
The caption segment that says “Don’t forget that SPACE is an element of hierarchy (placement on the grid, line spaces, indents, etc).” is helpful to me again because I sometimes get confused with the spacing and placement of things
Type sizes video:
“Try mixing up the order of small, medium, and large type in your layouts.” is a really simple concept that I somehow haven’t thought of before, watching the video and seeing how much better it looked when not even 3 lines were moved made it a lot better
So glad the examples helped you consider space and sizes anew.
