The View Transition API lets you update the DOM in a single step, while generating an animated transition between the two states. These kinds of transitions were a frequently-requested feature from developers, including me, and I think we've managed to land it in a way that balances good defaults with extensibility and customization. That sounds like we're patting ourselves on the back, but developer feedback was key to the design of this feature. An earlier prototype of this feature was much less flexible, and folks (like you?) who took the time to play with the prototypes and provide feedback triggered a total rethink. Thank you!

There are other trigonometry functions in the pipeline — including tan() — so why focus just on sin() and cos()? They happen to be perfect for the idea I have in mind, which is to place text along the edge of a circle. That’s been covered here on CSS-Tricks when Chris shared an approach that uses a Sass mixin.

It can seem intimidating, but once you know how, manual accessibility testing can become quicker and easier.
