What this module covers

5 steps · Tailwind CSS

  1. Step 1. Lesson: Responsive Tailwind

    Apply mobile-first breakpoint variants, responsive visibility, adaptive columns, and size constraints. Learning objectives - Recognize when responsive tailwind is the right tool. - Explain the role of md:, lg:, hidden. - 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.

    Apply mobile-first breakpoint variants, responsive visibility, adaptive columns, and size constraints. 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 responsive tailwind.

  2. Step 2. Quiz: Responsive Tailwind

    Check your understanding of Responsive Tailwind.

    Unprefixed utilities target mobile; breakpoint-prefixed utilities apply from that minimum width upward. 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: Responsive Tailwind

    Make a mobile-first layout that changes visibility, columns, spacing, and type at md and lg breakpoints.

    This exercise turns the Responsive Tailwind 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 md: and lg: and hidden?

  4. Step 4. Review lab: Explain & improve Responsive Tailwind

    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 md:, lg:, hidden 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 md:, lg:, hidden clearly?

  5. Step 5. Mini project: Responsive Tailwind

    Build a responsive marketing page with mobile navigation, tablet cards, and a wide desktop feature layout.

    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 responsive tailwind skills?
