I really like like flexbox, it sometimes feels like a game or a riddle.
It makes it easier that some of the material is not 100% new to me at this point. I feel like the repetition is solidifying things and allowing me to add more layers without becoming overwhelmed. The same with Figma. I did struggle with converting may first desktop version to tablet(and have yet to do the mobile), so I think that is an area I can become more efficient in as well.
