CSS
Vertically and Horizontally Center Content with Flexbox
Learn the simplest and most robust method to perfectly center any content both vertically and horizontally within its parent container using CSS Flexbox properties.
.center-container {
display: flex;
justify-content: center; /* Centers horizontally */
align-items: center; /* Centers vertically */
min-height: 100vh; /* Example: takes full viewport height */
background-color: #e0e0e0;
}
.centered-content {
padding: 30px;
background-color: #fff;
border-radius: 10px;
box-shadow: 0 4px 8px rgba(0, 0, 0, 0.1);
text-align: center;
font-family: sans-serif;
}
How it works: This highly practical snippet demonstrates how to achieve perfect centering using Flexbox. By applying `display: flex` to the parent container, `justify-content: center` centers child items along the main axis (horizontally by default), and `align-items: center` centers them along the cross axis (vertically by default). Setting a `min-height` on the container (e.g., `100vh`) ensures there's enough space for the centering to be visible.
