 # [3.0.0](https://github.com/vuejs/repl/compare/v2.9.0...v3.0.0) (2023-11-30)
 
+### Features
+
+* auto import css + split editor css from main component ([7322589](https://github.com/vuejs/repl/commit/7322589b64742bf8246a0ac4f5bf65e3e991e63f))
+
+  This change splits up the CSS between the main Repl component and the two
+  editors. This avoids including Monaco Editor css when using CodeMirror, and
+  vice-versa. In addition, CSS will be auto imported when the relevant
+  JS entries are imported.
+
+  To avoid having to separately import all the CSS, the generated JS now
+  automatically imports the CSS for you. This is breaking because it makes the dist files require a build system that can handle CSS imports from JS.
