[html] Div vertical scrollbar show

I am wondering how its possible to permanently show the vertical bar of a div (greyed out if there is no scrolling) similar to our regular bars. Basically I am trying to place an entire website in a div (like gmail/facebook), so if the page is not long enough the whole page shifts because of the lack of the vertical scroll bar.

I need a solution to this problem. I tried overflow-y:scroll. But it doesn't seem to work at all.

Have you tried overflow-y:auto ? It is not exactly what you want, as the scrollbar will appear only when needed.

Always : If you always want vertical scrollbar, use overflow-y: scroll;

jsFiddle:

<div style="overflow-y: scroll;">
......
</div>

When needed: If you only want vertical scrollbar when needed, use overflow-y: auto; (You need to specify a height in this case)

jsFiddle:

<div style="overflow-y: auto; height:150px; ">
....
</div>
