    <p>CSS, or Cascading Style Sheets, is used to style HTML elements by controlling their layout, colors, fonts, and overall appearance. CSS can be applied in three primary ways:</p>
    <!-- Inline CSS -->
    <h1 style="color: red;">This is Inline CSS</h1>

    <!-- Internal CSS -->
    <p class="internal-style">This is styled using Internal CSS.</p>

    <!-- External CSS -->
    <div class="external-style">This is styled using External CSS.</div>
</body>
