Sticky footer

Sticky footers are a popular way of displaying notices. Notices placed in the footer are less likely to obscure page elements like navigation bars, branding, and banner ads. In addition, sticky footers do not cause layout shifts when they are inserted into the page.

<div id="banner" class="banner">
    <button id="close-button" class="close-button" aria-label="close" tabindex="0">✕</button>
    <div>
        <h1>Notice</h1>
        Lorem ipsum dolor sit amet.
    </div>
</div>
 
document.getElementById("close-button").onclick = () => {
    document.getElementById("banner").style.display = "none";
}
 
body {
    font-family: system-ui;
    padding: 2em;
    overscroll-behavior-y: none;
    background-color: #f4f4f4;
}
.banner {
    position: fixed;
    left: 0;
    bottom: 0;
    right: 0;
    padding: 1rem;
    background-color: white;
    box-shadow: 0 0 10px rgba(0,0,0,0.2);
}
.close-button {
    background: transparent;
    border: none;
    padding: 1em;
    font-size: 1em;
    position: absolute;
    right: 0;
    top: 0;
    cursor: pointer;
}
