This **html.scala** 3.x provides the `html"""..."""` interpolation for creating reactive HTML templates. It is a reimplementation of `@dom` and `@html` annotation in [Binding.scala](https://github.com/ThoughtWorksInc/Binding.scala), supporting Scala 3. The typing rules are also improved, preventing red marks in IDEs.
9+
10+
For Scala 2 users, use `html.scala` 2.x instead.
