In web design, a footer is a section typically located at the bottom of the page that can contain copyright information, navigation links, contact information, and other elements. Using CSS, you can create a footer that remains at the bottom of the page even when the user scrolls, known as a fixed or sticky footer.

CSS Code for Fixed Footer

Here's an example of how to create a fixed footer using CSS:

And the corresponding HTML:

The position: fixed; style ensures that the footer remains in place at the bottom of the viewport regardless of scrolling. The left: 0; and bottom: 0; styles position the footer at the bottom-left corner of the viewport, while width: 100%; ensures it spans the full width of the screen.

Additional Styling and Structure

You can further style the footer to match your website's design and include additional elements such as authorship information, contact links, or a sitemap. The <footer> HTML tag is semantically appropriate for such content, and you can style it using CSS to match your design preferences.
