i was googling when i came across this.. the following image & never before or after that saw it…
this is a screen shot of google results in firefox

one result was scrollable with in itself…
see the scroll bar.. how can i achieve this scroll-bar…
we can have scrolling inside Divs but Firefox doesn’t let CSS styling of scroll-bar & it screws the look & feel of the page…
jQuery UI can knock this out of the park. Check out their slider.
All of their widgets are ARIA-enabled and keyboard accessible, try using arrow keys and page-up/page-down on the example.
You can get this working on your website in 20 minutes. Less if you are already familiar with jQuery UI.
