Centering Elements Horizontally and Vertically

While modern CSS tools like flexbox and grid are often used for centering, you can also center elements both horizontally and vertically using margins. This technique is particularly handy when working with block-level elements with fixed dimensions.

.container {
    height: 100vh; /* Full viewport height for vertical centering */
    position: relative; /* Establish a context for absolute positioning */
}

.centered-element {
    width: 200px; /* Fixed width */
    height: 100px; /* Fixed height */
    position: absolute;
    top: 0;
    left: 0;
    bottom: 0;
    right: 0;
    margin: auto; /* Automatically centers the element */
    transition: margin-left 0.3s ease-in-out; /* Smooth transition for margin changes */
}

In this setup, the margin:auto; rule automatically adjusts the margins to center the element within its container. This approach is particularly useful…
