1. Step 1. Lesson: Reusable Component System

   Build maintainable component variants, composition patterns, consistent states, and reusable interface primitives. Learning objectives - Recognize when reusable component system is the right tool. - Explain the role of component, variant, class. - Build a small working example before combining it with a larger interface. - Identify one accessibility, maintainability, or error-handling improvement. Read the example, predict what it will do, then complete the small change described in the check question.

   Build maintainable component variants, composition patterns, consistent states, and reusable interface primitives. In HTML + CSS, make the state/interaction visible in the UI so completion is easy to verify.

   Check yourself: [HTML + CSS] Use the example to demonstrate reusable component system.

2. Step 2. Quiz: Reusable Component System

   Check your understanding of Reusable Component System.

   Extracting meaningful repeated patterns improves consistency without hiding every utility. In HTML + CSS, make the state/interaction visible in the UI so completion is easy to verify.

   Check yourself: [HTML + CSS] Complete the knowledge check.

3. Step 3. Exercise: Reusable Component System

   Design button, input, alert, badge, and card variants with consistent sizes, states, and focus treatment.

   This exercise turns the Reusable Component System lesson into a working code change. In HTML + CSS, make the state/interaction visible in the UI so completion is easy to verify.

   Check yourself: [HTML + CSS] Does the solution use component and variant and class?

4. Step 4. Review lab: Explain & improve Reusable Component System

   Rebuild the exercise without copying the solution. Then improve it in two ways: make the code easier to understand and add one useful edge case, responsive behavior, accessibility improvement, or error state. Finally, write a short explanation of how component, variant, class work together.

   Rebuilding from memory and improving an edge case turns recognition into durable skill. In HTML + CSS, make the state/interaction visible in the UI so completion is easy to verify.

   Check yourself: [HTML + CSS] Does the improved version still use component, variant, class clearly?

5. Step 5. Mini project: Reusable Component System

   Build a documented mini design system that can style an entire dashboard without one-off utility combinations.

   The mini project combines the module lesson, quiz, and exercise into one portfolio-ready result. In HTML + CSS, make the state/interaction visible in the UI so completion is easy to verify.

   Check yourself: [HTML + CSS] Does the project apply the module's reusable component system skills?
