Trying to get the header area to go from solid to opaque after scrolling down a certain number of pixels. In the case of the test, it is 200 pixels. In Chrome, IE, Safari it is working properly or at least quite better than in Firefox. Sometimes it works but is very delayed in Firefox and other times it takes a bit of scrolling up and down an few times to make it work properly.
Please view in Chrome or something other than FF and then view in Firefox to see the issue or delay.
Any help with my jquery, etc. would be super helpful.
