I installed Mellow from the Site Library, as I love the line under the navigation menu that highlights each item.
However, the thicker highlighted portion appears differently in Safari than in Chrome and Firefox. In the latter two, it is white. In Safari–on mac as well as iPad and iPhone–it turns an ugly gray.
I haven’t messed with the additional CSS that was loaded with Mellow except to make the line slightly thicker.
Thanks for any help!
