✅ 1. Center Image Horizontally Using text-align: center

If the image is inside a block container (like a <div>), the easiest method is:

✅ HTML:

<div class="center-container">
  <img src="image.jpg" alt="Centered Image">
</div>

✅ CSS:

.center-container {
  text-align: center;
}

📌 The image is inline by default, so this works like centering text.

✅ 2. Center Image Using margin: auto and display: block

When you want full control using margins:

img.center-image {
  display: block;
  margin: 0 auto;
}

<img src="image.jpg" alt="Centered Image" class="center-image">

✅ This method is cleaner and more reliable in most layouts.

✅ 3. Center Image Vertically and Horizontally Using Flexbox

Flexbox is a modern, powerful layout system perfect for centering.

✅ CSS:

.flex-center {
  display: flex;
  justify-content: center; /* Horizontal */
  align-items: center;     /* Vertical */
  height: 400px;
}

✅ HTML:

<div class="flex-center">
  <img src="image.jpg" alt="Centered with Flexbox">
</div>

✅ Ideal for cards, modals, and hero sections.

✅ 4. Center Image with CSS Grid

A super-simple modern method:

.grid-center {
  display: grid;
  place-items: center;
  height: 400px;
}

<div class="grid-center">
  <img src="image.jpg" alt="Centered with Grid">
</div>

🎯 This centers the image both horizontally and vertically with just one line!

✅ 5. Responsive Centering

Make sure your centered image works across devices:

.responsive-center {
  display: block;
  max-width: 100%;
  height: auto;
  margin-left: auto;
  margin-right: auto;
}

✅ This ensures your image stays centered and scales well on different screen sizes.
