The View Transition API is amazing... but we're bad at it

Bad at CSS

View Transitions are a brand new totally rad cutting edge feature in the browser. They allow you to specify animation states from one state to another a lot easier than ever before. But guess what? We’re still bad at them. In this episode Adam explains how awesome View Transitions are by explaining the difficulties of the FLIP animation technique. Adam then discusses how he struggled, but finally succeeded, to build a morphing button with View Transitions. Oh and we also discuss how Adam isn’t a TypeScript fan, but you’ll have to listen to the end for that part.
