Master How to Center an Image in HTML (5 Real-World Fixes You’ll Love)

Want to master the art of how to center an image in HTML without breaking your layout or pulling your hair out?

Whether you’re designing a modern landing page, showcasing a product, or just trying to align a logo in the middle of a header, image alignment is one of those deceptively tricky tasks in web design. Beginners often expect a simple solution, but even seasoned developers sometimes stumble into alignment pitfalls that ruin responsive designs or break on mobile.

In this comprehensive guide, you’ll discover five real-world fixes—each with working code examples—to help you confidently center images both horizontally and vertically. You’ll also learn why common centering methods fail, how to avoid outdated techniques, and which modern CSS tools (like Flexbox and Grid) make alignment effortless across all screen sizes.

Why Centering an Image in HTML Can Be Frustrating

Let’s start with what developers usually struggle with—and why it happens.

1. text-align: center Doesn’t Work As Expected

Why it happens:
text-align only affects inline or inline-block elements. <img> is inline by default, but if it’s floated or styled as display: block, text-align won’t apply. Also, the parent must be block-level.

Fix:
Wrap your image in a block-level element and apply text-align: center to it.

<div style="text-align: center;">
  <img src="centered-image.jpg" alt="center image in HTML">
</div>

2. The Image Is Centered Horizontally, But Not Vertically

Why it happens:
CSS has no default vertical centering mechanism for block-level elements. Vertical space isn’t auto-balanced like horizontal space.

Fix:
Use Flexbox or Grid to unlock vertical alignment.

<div style="display: flex; justify-content: center; align-items: center; height: 300px;">
  <img src="centered-image.jpg" alt="center image in HTML">
</div>

3. Images Break on Mobile

Why it happens:
Images use fixed dimensions by default. On small screens, they can overflow or distort.

Fix:
Use responsive styles.

<img src="responsive.jpg" alt="responsive centered image" style="max-width: 100%; height: auto;">

4. Layout Looks Good on Desktop, But Breaks on Mobile

Why it happens:
Using fixed widths or outdated centering methods (like margins or absolute positioning) makes your layout brittle.

Fix:
Pair Flexbox/Grid with scalable units.

<div style="display: flex; justify-content: center;">
  <img src="centered-mobile.jpg" alt="center image HTML mobile" style="max-width: 100%; height: auto;">
</div>

The Best Ways to Center Images in HTML

1. text-align: center (Inline Image)

<div style="text-align: center;">
  <img src="inline.jpg" alt="center image in HTML">
</div>

2. margin: auto with display: block

<img src="block.jpg" style="display: block; margin: 0 auto;" alt="HTML block centered image">

3. Flexbox (Full-Axis Centering)

<div style="display: flex; justify-content: center; align-items: center; height: 300px;">
  <img src="flex.jpg" alt="center image in HTML">
</div>

4. CSS Grid (Cleanest Method)

<div style="display: grid; place-items: center; height: 300px;">
  <img src="grid.jpg" alt="grid center image">
</div>

5. Absolute Position + Transform

<div style="position: relative; height: 300px;">
  <img src="cta.png" style="position: absolute; top: 50%; left: 50%; transform: translate(-50%, -50%);" alt="centered overlay image">
</div>
