Phones tend to cache css moreso than the web pages. I usually have to manually flush the local browser files to get changes to show.
i opened up the style.css file directly and that seemed to reload? but i did like 5 other things in the same 30 seconds so not positive that was it. cheeeers
cleaned up styles for whole site, def missed some spots, iching is kinda broken more now, otherwise much simpler and easier to manage
