CSS Background Attachment

The background-attachment property determines whether the background image scrolls with the page or remains fixed. A fixed background can create a parallax effect, giving your site a more dynamic and engaging appearance.

Key Topics

Scroll

background-attachment: scroll; is the default behavior. The image moves as the user scrolls down the page.

Fixed

background-attachment: fixed; keeps the image in place while the foreground content scrolls, creating a subtle parallax-like effect.

<body>
    <h1>Fixed Background Heading</h1>
    <p>As you scroll, the background image remains in place while the text moves. This creates an immersive effect, making the background feel more dynamic.</p>
    <p>Keep scrolling to experience the effect further.</p>
    <p>This technique can enhance visual storytelling on your webpage.</p>
</body>
</html>

Explanation: The fixed background remains static while text and other elements scroll over it, producing a distinctive visual effect that can emphasize the content against a stable backdrop.

Local

background-attachment: local; makes the background scroll with the element’s content. This is less common but can be useful for scrollable containers with their own backgrounds.

Key Takeaways

  • Scroll (default): Background moves with the page.
  • Fixed: Background stays in place, creating a striking visual effect.
  • Local: Background moves with the element’s scrollable container.
