I am new in jquery ui and have two questions.

 

1. What is the relationship between http://jqueryui.com/ and this website http://flowplayer.org/tools/index.html. I feel the latter is pretty impressive.

 

2. For the homepage of http://flowplayer.org/tools/index.html, if I shrink my browser horizontally in IE, no horizontal scroll bar shows up. How is it implenented to achieve this effect?

 

Thanks!
