• Code Example: Writing locally scoped CSS and importing it cleanly in JavaScript:

  /* Button.module.css */
  .errorButton {
    background-color: #ef4444;
    color: white;
  }
  
  /* Component.jsx */
  import styles from './Button.module.css';
  const MyButton = () => <button className={styles.errorButton}>Delete</button>;

9. PurgeCSS: The Ultimate Bloat Eliminator 🗑️⚡

  /* Output */
  .box {
    display: -webkit-box;
    display: -ms-flexbox;
    display: flex;
    -webkit-user-select: none;
    -moz-user-select: none;
    -ms-user-select: none;
    user-select: none;
  }

FAQ ❓

Q1: How do I choose between Tailwind CSS and traditional CSS Modules for my project?
A: Choosing depends heavily on your team’s workflow preferences and project goals. Tailwind CSS excels at rapid prototyping and maintaining design consistency through strict atomic utility constraints without writing external stylesheet files.
