[chromium-discuss] Mobile devices: zoom and javascript scroll

[Nikita Pankov]

Hello,

Recently I met strange (from my point of view) behaviour in Chrome: When
you zoom the page, the screen gets smaller than the viewport and therefore
needs to panned to view parts of the viewport's content.
But when you call functions like element,scrollIntoView() (or even
window.scroll()): this scrolls the page in viewport but leaves the screen
in the same position. So element.scrollIntoView() seems to be inadequate.

I couldn't find any issues in the tracker and couldn't find a way to move
the screen around the viewport using javascript.
So I can't get my element in the user's attention area in the center of the
screen.

Thank You.

I thought scrollIntoView was supposed to ensure the element was visible in
the visible viewport (not just the layout viewport). +bokan

This is all about Visual Viewport API, but unfortunately this is read only
- I can see no way to move the visible viewport :( Only touch event
simulations.
