fix for scroll bars on webkit & Mac OS X Lion

[LondonLight.org]

Hi

The HTML file generated by Pano2VR includes this in the CSS:

Code: Select all

			/* fix for scroll bars on webkit & Mac OS X Lion */ 
			::-webkit-scrollbar {
				background-color: rgba(0,0,0,0.5);
				width: 0.75em;
			}
			::-webkit-scrollbar-thumb {
    			background-color:  rgba(255,255,255,0.5);
			}

Can't find any info on this.
What is wrong with scrollbars on WebKit and Mac OS X Lion, what triggers the problem, and which versions are affected?
