Why I spent years trying to make CSS states predictable
The article discusses the challenges of managing CSS states and the complexity that arises when multiple states overlap. It introduces a tool called Tasty, which aims to simplify the process by allowing developers to define component states declaratively. This approach eliminates selector conflicts and makes extending components easier.
- ▪CSS states can become complex when multiple states overlap, leading to conflicts.
- ▪The author developed a tool called Tasty to express component states as a map, simplifying selector logic.
- ▪Tasty compiles state maps into unambiguous selectors, preventing conflicts and easing component extension.
