Split Canvas makes scroll feel like a cut through the visual field. It is for pages where the transition between states matters.
Use Split Canvas when the page message benefits from a visual split that feels deliberate. Creative studios, AI launches, and experimental brand pages can use it to frame contrast, reveal, or transformation. The page job is contrast: two sides of the idea should feel connected by the interaction.
The production risk is canvas dependency. If the split effect fails, the core message, headline, and CTA must still exist in HTML and remain visually complete.
An AI launch page contrasting before-and-after product states: Split Canvas frames the transformation as a designed reveal rather than a static comparison. The outcome is contrast: the visitor feels the shift before reading the detail.
Best Used For
Brand sections where the change between two visual states is the point of the scroll moment.
Before/after and state-change moments where the cut is the message.
Split Canvas creates a concrete scroll outcome that a static section would not deliver.
Not For
Not for content where the before/after state is not obvious without motion.
Not for pages where split motion would hide the CTA or interrupt reading.
Performance Budget
Animate transform and opacity, avoid layout reads in scroll handlers, pre-size media, and clean up timelines/listeners when the route changes.
Accessibility and Mobile
The animated sequence must match DOM order. On mobile, replace pinned or horizontal mechanics with stacked sections, native swipe, or static cards.
Common Mistakes
Putting meaningful copy only inside a canvas layer.
Letting the seam hide the before/after comparison.
Using a split when there is no real two-state story.
Frequently Asked Questions
What makes Split Canvas different from a standard scroll reveal?
Scroll acts like a cut through the visual field, splitting and shifting the canvas between two states rather than revealing one element. The transition between states is the message. Use it where the change itself is what you want noticed.
How should Split Canvas simplify on mobile devices?
Reduce the split travel and ensure the two states stack or transition cleanly on a narrow screen. Keep any text content in the DOM, not painted into the canvas. Reduced-motion users should see the end state directly.
What should developers test before shipping Split Canvas?
If a real canvas is used, confirm it pauses offscreen, cleans up on route change, and exposes meaningful HTML alongside it. Check the split doesn't clip content at the seam. Verify the static fallback shows the final state.
Which content structure works best with Split Canvas?
A two-state moment — before/after, open/closed, or a strong scene change — where the cut dramatizes a transition. It's wrong for continuous reading or many states. Keep it to a single, clear split.
When should I avoid Split Canvas even if the preview looks good?
Avoid it where the meaning lives in text that would end up inside a canvas, on content-dense pages, or where the seam could hide information. If there's no real two-state story, the cut is empty. Skip it when a fade would do the same job.
