Display and layout rules aren’t difficult at all. Maybe I’m just not experienced enough. I’ve been a web dev for nearly a decade now and I feel like I’ve got the hang of it. That being said, I don’t work on projects that have to work on everything from a Nokia to an ultra wide monitor. We shoot for a few common sizes and hope it clears between edge cases nicely. What is an example of something that wraps randomly?
Why didn’t you like Hashicorps Vault? I want to know for my own edification.
