Build a Sticky Footer Layout with CSS Flexbox

Implement a classic sticky footer design ensuring the footer always stays at the bottom of the viewport, even with sparse content, using Flexbox for robust layout management.

body {
    display: flex;
    flex-direction: column;
    min-height: 100vh; /* Ensure body takes full viewport height */
    margin: 0;
    font-family: sans-serif;
}

header {
    background-color: #333;
    color: white;
    padding: 1em;
    text-align: center;
}

main {
    flex-grow: 1; /* This makes the main content push the footer down */
    padding: 1em;
}

footer {
    background-color: #eee;
    padding: 1em;
    text-align: center;
}

How it works: This snippet creates a 'sticky footer' layout where the footer remains at the bottom of the viewport, even if the main content area is short. By setting `display: flex` and `flex-direction: column` on the `body`, and then `flex-grow: 1` on the `main` element, the main content area expands to fill all available vertical space, pushing the footer down. `min-height: 100vh` on the body ensures it occupies at least the full viewport height.
