🎯 Method 1: Center a Button Horizontally Using Text Align

If your button is inside a container like a <div>, you can center it with text-align: center.

✅ HTML:

<div class="button-container">
  <button>Click Me</button>
</div>

✅ CSS:

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

Result: The button will be centered horizontally inside the container.

🎯 Method 2: Center a Button Horizontally Using Margin

You can also center a block-level button using auto margins.

✅ CSS:

button {
  display: block;
  margin: 0 auto;
}

⚠️ Make sure the button is display: block or display: inline-block for this to work effectively.

🎯 Method 3: Center a Button Vertically and Horizontally Using Flexbox

For both vertical and horizontal centering, Flexbox is the most powerful and responsive method.

✅ HTML:

<div class="flex-center">
  <button>Submit</button>
</div>

✅ CSS:

.flex-center {
  display: flex;
  justify-content: center; /* horizontal */
  align-items: center;     /* vertical */
  height: 100vh;           /* full height of the screen */
}

Result: The button will be perfectly centered in the middle of the page or container.

🎯 Method 4: Center a Button Using Grid

CSS Grid can also center elements easily:

✅ CSS:

.grid-center {
  display: grid;
  place-items: center;
  height: 100vh;
}

This will center the button both vertically and horizontally inside the container.
