Does Webflow have limitations when it comes to displaying the entire height of a div with fixed positioning, and can it be used to replicate an effect similar to the splash image on the Stanford site?

Webflow supports fixed-position elements, but you must configure the height and layout carefully to fully display them across different screen sizes. Here’s how to achieve a full-height splash image effect similar to the Stanford.edu homepage.

1. Understand Fixed Positioning in Webflow

• Fixed positioning pins an element to a location relative to the viewport, regardless of page scroll.
• If your fixed div doesn't show full height, it’s usually because height: 100% isn’t inherited correctly — the parent elements might not have height defined.
• To reliably show full-page height, set the element’s height to 100vh (100% of the viewport height), not 100%.

2. Set Full-Height Div for Splash Section

• Create a Div block and give it a class name (e.g., splash-section).
• In the Style panel, apply the following:
• Position: Fixed
• Top: 0, Left: 0, Right: 0
• Height: 100vh
• Z-index: Ensure it's above other content if needed.
• Add background image settings:
• Background image: Set to Cover, Center Center, No Repeat.
• Optional: Add overlay with a gradient or semi-transparent color.

3. Control Scroll Behavior

• Stanford’s site uses a splash image that appears initially and then fades or scrolls into the rest of the content.
• In Webflow, you can:
• Place the splash div above the normal page content, and use scroll interactions (via Webflow’s Interactions panel) to fade it out or hide it on scroll.
• Alternatively, place the splash inside a Section at the top of the page (instead of fixed), and use min-height: 100vh. It will scroll away naturally.

4. Make It Responsive

• Ensure the min-height: 100vh or fixed height viewport adapts to all breakpoints.
• For mobile, reduce heavy images or apply a different layout if needed using Webflow’s responsive settings.

5. Optional: Add a Scroll Cue or Animation

• Stanford uses a visual cue (like a small arrow) and smooth transition into content.
• You can add a scroll animation or anchor link to the next section using a button or scroll arrow with scroll to section interaction.

Summary

Webflow can fully replicate a fixed or full-height splash section like Stanford’s if you use 100vh height, fixed or relative positioning, and interactions for scroll or fade effects. Just avoid relying on height: 100% without constraining parent elements — always prefer viewport-based units for splash effects.
