Centering Elements with Flexbox (Horizontal & Vertical)

Learn the most efficient way to center any element perfectly within its container using a combination of Flexbox properties for both horizontal and vertical alignment.

.container {
  display: flex;
  justify-content: center;
  align-items: center;
  height: 100vh; /* Example: full viewport height */
  width: 100%;
  background-color: #f0f0f0;
}

.item {
  width: 100px;
  height: 100px;
  background-color: #007bff;
  color: white;
  display: flex;
  justify-content: center;
  align-items: center;
  font-size: 1.2em;
}
How it works: This snippet demonstrates perfect centering using Flexbox. Apply `display: flex;` to the parent container. `justify-content: center;` aligns items along the main axis (horizontally by default), and `align-items: center;` aligns them along the cross axis (vertically by default). Setting the parent's `height` ensures there's space for vertical centering.
