Custom Scroll Bar Logic

[rupert]

Each text-line is a div. Calculate, how may pixel this div needs vertical, e.g. by drawing a test-div.
Create a scrollable div, the scene (Browser.Dom - browser 1.0.2). In this scene display the divs containing lines.

Now the optimization:
Merge all divs with lines before the viewport to one big div, without any content.
Similar merge for all divs after the viewport.

So only the viewable divs with lines are rendered.

That sounds like a good idea and has the advantage that you just use overflow: scroll on the containing div, no need for putting scroll bars in separate divs. Thanks.
