Modify scrollbar/Navigation Bar

Hi!
I'm a beginner, still learning to understand how to use krpano viewer/tools and trying all the stuffs one by one, as I know nothing about code. I found this forum really helpful in understanding the documentations. And also the forumers are friendly :)

I'm currently trying to modify the "Corfu Tour" scrollbar in example folder. I want to remove the white lines at top and bottom border, and it works by removing some codes on XML.

I also want to remove the space between the scrollbar and bottom edge of the image (please see attachment), so the container will move down to the bottom edge of the image/frame.I still don't know how to do this (I think I should set the ordinat code?). Can you please help me?

Thank you,
Don

How to do this both of the tour and next future?

Actually I'm experimenting, many things I will modify, but I think it's
enough for this night. (I'm working on changing the opacity as well, it
works well!)
Thanx for your reply, buddy!

Regards,
Don

Uh.. just crossed my mind... If I move the scrollbar to the edge of bottom image/frame, it might be difficult for some clients when he clicks the button. What about another option by filling the space with the BG color?

It works well! Thanx :)

By the way, I find annoying tooltips "Allow or deny fullscreen" whenever I click the fullscreen button. I don't know where it comes?! How can I remove it?

Regards,
Don
