This lesson

This lesson teaches Production build habits—the ideas, syntax, and habits you need before moving on in Sass.

Interviewers and code reviewers expect you to connect Production build habits to real trade-offs—not only syntax.

You will apply Production build habits in contexts like: Mature front-end codebases, design systems, and teams that compile SCSS in CI or locally.

Write SCSS, compile in the playground, inspect CSS output, and reinforce with lesson quizzes.

When intermediate lessons feel comfortable and you are ready for production-style trade-offs.

Compile once in CI — commit CSS or ship from build artifact
Use --style=compressed for production
Source maps for debugging
Stylelint for SCSS

Going deeper

In production Sass work, Production build habits matters when documents, stylesheets, or apps must stay maintainable across teams and releases—not only in isolated demos.

Common pitfalls

Watch for copy-paste configs, skipping validation or tests, and mixing concerns (structure vs presentation vs behavior) in one layer.

Practice

Apply one technique from this lesson in the playground.
Write one interview-style sentence explaining when you would use production build habits on a real project.
