Why CSS Grid Is Not Working 11 Fixes Developers Actually Need

CSS Grid is powerful, but small syntax mistakes break layouts. If your grid isn’t aligning, not creating columns, or collapsing unexpectedly, here’s what to check.

1️⃣ Missing display: grid

.container {
  display: grid;
}

2️⃣ No Grid Template Defined

.container {
  display: grid;
  grid-template-columns: 1fr 1fr 1fr;
}

3️⃣ Grid Items Not Placing Correctly

.item {
  grid-column: 1 / 3;
}

4️⃣ Using Auto Without Understanding

Use repeat() for cleaner layouts:

grid-template-columns: repeat(3, 1fr);

5️⃣ Overlapping Items

Check manual row/column placement.

6️⃣ Implicit Grid Issues

Use:

grid-auto-rows: minmax(100px, auto);

7️⃣ Not Understanding fr Units

1fr distributes remaining space evenly.

8️⃣ Gap Not Working

gap: 20px;

9️⃣ Alignment Issues

justify-items: center;
align-items: center;

🔟 Mobile Layout Breaking

@media (max-width: 768px) {
  .container {
    grid-template-columns: 1fr;
  }
}

11️⃣ DevTools Grid Inspector

Use browser Grid inspector to visualize layout areas.
