When showing diff in the Config Change popup, the content for "Current" vs "New" and "Current" vs "Recommended" columns don't line up properly. See the attached screenshots. The left edge for the content box of "Current" / "Recommended" should be flush with the left edge of the header.
The color palette used for the diff looks a bit out of place in that they don't mesh well with the rest of the colors used in Ambari Web. We shpuld use the standard colors that we use elsewhere for warn, alert, success, etc.
