 ## Why Scss-to-css
-> For some small project or teaching speech. It's too fat to deploy a webpack env.
-> Now, `scss-to-css` help us to compile scss file to css file at a none webpack project and autoprefixer.
+> For small projects, various engineering tools such as webpack are too heavy and cumbersome to configure. And a lot of modules have to be installed.
+> Sometimes, we just want to simply use the convenience brought by scss. So for this purpose, I wrote a vsc plug-in, which can be automatically compiled into a css file (stored in the current directory by default) when the scss file is saved, and the browser prefix is ​​automatically completed.

 ## 依赖
-> 3.x之后, 弃用libsass,改为node-sass, 但由于vscode的限制, node-sass在拓展里使用会有问题, 所以需要手动全局安装。
