Currently the WebKit Bot Watcher Dashboard uses the CSS property z-index to have the ring overlay image (<https://build.webkit.org/dashboard/Images/PlatformRing.png>) painted on top of each platform icon (e.g. <https://build.webkit.org/dashboard/Images/Yosemite.png>). We remove the use of the CSS property z-index by taking advantage of the transparency in the ring image and ordering the DOM such that the platform icon is before the ring image.
