Flexible Sticky Footer Layout with Flexbox

Build a classic sticky footer layout ensuring the footer always rests at the bottom of the viewport, even with minimal content, and pushes down with more content.

html, body {
    height: 100%;
    margin: 0;
}

body {
    display: flex;
    flex-direction: column;
}

.content-wrap {
    flex: 1 0 auto; /* Grows to fill available space, never shrinks below content */
}

.site-footer {
    flex-shrink: 0; /* Prevents footer from shrinking */
    padding: 1rem;
    background-color: #f0f0f0;
    text-align: center;
}

How it works: This Flexbox solution creates a sticky footer. By setting `display: flex;` and `flex-direction: column;` on the `body`, content flows vertically. `height: 100%;` on `html, body` ensures the body takes full viewport height. The `.content-wrap` (main content area) uses `flex: 1 0 auto;` to `flex-grow` and fill any available space, pushing the footer down. The `.site-footer` has `flex-shrink: 0;` to prevent it from shrinking when space is limited, ensuring it always maintains its intended height.
