   npm is the standard package manager for JavaScript projects, including Tailwind.

3. Final Answer:

   npm -> Option C

4. Quick Check:

   Tailwind installation uses npm [OK]

medium

A. Using @tailwind instead of @import

B. Not running the build process to generate CSS

C. Including Tailwind CSS twice in HTML

   Tailwind requires running a build tool (like PostCSS) to process directives and generate final CSS.

2. Step 2: Identify why styles don't apply

   If you add directives but skip the build step, no CSS is generated, so styles won't show.

3. Final Answer:

   Not running the build process to generate CSS -> Option B

4. Quick Check:

   Build process missing = no styles applied [OK]

Hint: Always run build after adding Tailwind directives [OK]

Common Mistakes:

• Confusing @tailwind with @import usage
• Including Tailwind CSS multiple times causes no effect
• Thinking writing classes alone applies styles
