    <h2>10. Grid Layout</h2>

    <h3>I. Grid Container & Items</h3>
    <p><strong>Explanation:</strong> Grid layout ek 2-dimensional layout system hai jisme rows aur columns dono ka control hota hai. Parent ko <code>display: grid</code> dene par wo container ban jata hai.</p>

    <textarea id="code1">
<style>
.grid {
  display: grid;
  grid-template-columns: auto auto auto;
  gap: 10px;
  background: lightgray;
  padding: 10px;
}
.box {
  background: #007bff;
  color: white;
  padding: 20px;
  text-align: center;
  border-radius: 8px;
}
</style>
<div class="grid">

  <div class="box">2</div>
  <div class="box">3</div>
  <div class="box">4</div>
  <div class="box">5</div>
  <div class="box">6</div>
</div>
    </textarea>
    <button onclick="runCode('code1', 'output1')">Run Code</button>
    <iframe id="output1"></iframe>

    <h3>II. Template Rows & Columns</h3>
    <p><strong>Explanation:</strong> <code>grid-template-columns</code> aur <code>grid-template-rows</code> se hum define karte hain kitni columns ya rows honi chahiye aur unka size kya hoga.</p>

    <textarea id="code2">
<style>
.grid {
  display: grid;
  grid-template-columns: 100px 200px 100px;
  grid-template-rows: 60px 60px;
  gap: 10px;
  background: #fce4ec;
  padding: 10px;
}
.box {

  <div class="box">D</div>
  <div class="box">E</div>
  <div class="box">F</div>
</div>
    </textarea>
    <button onclick="runCode('code2', 'output2')">Run Code</button>
    <iframe id="output2"></iframe>

    <h3>III. Item Placement & Spanning</h3>
    <p><strong>Explanation:</strong> Grid items ko specific row ya column me rakhne ke liye hum <code>grid-column</code> aur <code>grid-row</code> use karte hain. <br> Spanning ka matlab hai ek item multiple rows/columns tak faila ho.</p>

    <textarea id="code3">
<style>
.grid {
  display: grid;
  grid-template-columns: repeat(3, 1fr);
  gap: 10px;
  background: #e0f7fa;
  padding: 10px;
}
.item {
  background: #00acc1;
  color: white;
  padding: 20px;
  border-radius: 8px;
  text-align: center;
}
.span2 {
  grid-column: span 2;
}
</style>
<div class="grid">
  <div class="item">1</div>
  <div class="item span2">2 (spans 2 columns)</div>
  <div class="item">3</div>
  <div class="item">4</div>
</div>
    </textarea>
    <button onclick="runCode('code3', 'output3')">Run Code</button>
    <iframe id="output3"></iframe>

    <h3>IV. Auto-placement & Grid Areas</h3>
    <p><strong>Explanation:</strong> CSS Grid automatically items ko place karta hai agar aap manually jagah define na karo.<br>
    Grid Areas ka use karke hum naam se jagah define karke items ko uss area me daal sakte hain (like template design).</p>

  display: grid;

    "header header"
    "sidebar main"
    "footer footer";
