Pseudo-Smooth-Scrolling Demo 1/2

These pages demonstrate the pseudo-smooth-scroll effect, commonly seen on websites that use view transitions for elements larger than the viewport.

This can give the website the appearance of dynamic movement, but it can also be quite disruptive if it occurs unexpectedly.

Use the navigation bar on the left to explore Steps 1 through 4 and learn more about what causes this effect.

Take Step 1 to find out how to identify the pseudo-smooth-scroll effect on a web-site.

Disabling the group animation on the content element removes the pseudo-smooth-scroll effect. But the result won't look good: Now, instead of the current area of the old element, some other area is shown. The transition group jumps directly to the position of the new image, and for the old image shows what ever happens to be at that position in the old element.

So the old images jumps away from its current content, and even worse, the position shown instead might be empty if the screen was not rendered completely yet or while the snapshot of the old image was taken.
