Write SCSS and compile it to CSS in a cloud workspace.
Start coding free →SCSS (Sassy CSS) extends CSS with variables, mixins, nesting, and other features that make stylesheets easier to write and maintain. It is a preprocessor language: you write .scss files and compile them to regular CSS before serving a page. On RunCode, a workspace with Sass and VS Code is ready in under a minute, so you can write and compile SCSS without a local install.
Open a SCSS workspace →SCSS is fully compatible with standard CSS, so any existing stylesheet is valid SCSS. Variables let you define colors, font sizes, and spacing values once and reuse them across a project. Mixins are reusable blocks of styles you can include wherever needed, which cuts repetition and keeps CSS consistent. Nesting lets you write selectors that mirror your HTML structure, which is easier to follow than the flat selectors CSS requires. SCSS is often paired with build tools like Webpack or Vite, which watch .scss files and recompile automatically on save. The compiled CSS has no runtime dependency on SCSS, so there is nothing extra to ship to production.
