Different appearance when run on server
We are seeing different results in page appearance when running an application in the VS 2012 IDE versus once published to our server. Inset table borders and beveled buttons on the server, for example, are both rendered as thick black outlines in the IDE. Additionaly, objects that are centered when rendered by the server are left justified in the IDE in the design window. This lack of WYSIWYG is obviously making changes more difficult than they ought to be.
I was hopeful for suggestions for why this difference exists and what we need to do so that our development workstations produce the same results as our servers, not for help debugging specific CSS. Can this be simply corrected by copying some default css file or something similar from the server to our development workstations to make them look the same? Or is this just one of those things we're going to have to work around?
