How to build parallax scrolling in Bubble

Bubble doesn’t have a built‑in “parallax” property, but you can create real parallax scrolling using a Group or Image as a background layer plus a tiny piece of custom CSS inside an HTML element. The effect works by fixing the background image so it scrolls slower than the rest of the page.

Simple Working Setup (the core idea)

You place an HTML element inside the section where you want parallax, give it the size of the section, and apply background-attachment: fixed in CSS. Everything else (text, buttons, groups) sits on top like normal Bubble elements.

<div style="height:400px; 
            background-image:url('https://yourimageurl.com/pic.jpg');
            background-size:cover;
            background-position:center;
            background-attachment:fixed;">
</div>

Detailed steps in Bubble

• Drag a Group onto your page. This is your “parallax section.” Set it to a fixed height or minimum height.
• Inside that Group, insert an HTML element that covers 100% of the group (set width/height to stretch).
• Paste the code above into the HTML element. Replace the image URL with a real Bubble image’s “view” link or an external URL.
• Place your content (text, buttons) in a separate Group on top. Make that Group bring to front so it sits above the HTML block.
• If using responsive engine, keep the HTML element pinned to all sides so it expands with the parent Group.

Things beginners must know

• background-attachment: fixed is what creates the parallax effect. Without it, the image scrolls normally.
• On some mobile browsers, fixed background is disabled. Bubble can’t override this, so the effect may fall back to normal scrolling.
• You do not edit Bubble’s page-level HTML header for this — keep it inside an HTML element to avoid affecting other elements.
