/* Flexbox Method for Centering */
.flex-container {
display: flex;
justify-content: center; /* Horizontally centers content */
align-items: center; /* Vertically centers content */
min-height: 100vh; /* Takes full viewport height for demonstration */
border: 2px dashed #ccc;
}
.flex-item {
padding: 20px;
background-color: #007bff;
color: white;
font-size: 1.5rem;
}
/* Grid Method for Centering */
.grid-container {
display: grid;
place-items: center; /* Shorthand for align-items: center and justify-items: center */
min-height: 100vh; /* Takes full viewport height for demonstration */
border: 2px dashed #ccc;
}
.grid-item {
padding: 20px;
background-color: #28a745;

How it works: This snippet demonstrates two powerful CSS methods for perfectly centering an item within its container. The Flexbox method uses `display: flex`, `justify-content: center` (for horizontal alignment), and `align-items: center` (for vertical alignment). The Grid method offers a more concise solution with `display: grid` and the `place-items: center` shorthand, which sets both `align-items` and `justify-items` to `center`, making it incredibly efficient for single-item centering tasks.
