vbulletin-chrome.css

[webcosmo]

I have created a custom style. To make changes with the design I need to set some styles. I need to set the padding on the navbar. The searchbox seem to have a float right which is not working if I set padding for navbar.

I cant find any style to set using the stylemanager that would take care of this, but apparently there are some classes in vbulletin-chrome.css which if I do modify serves the purpose.

Is it ok if I change vbulletin-chrome.css file? Or any issues I should know of.
