When speaking of Object Oriented CSS (OOCSS), what elements of CSS are considered “structure” and which are considered “skin”? I am probably a bit of a gray area thinker and while an element like width easily falls in to the structure category and color or background fit into the skin category, what about an element like border which affects both structure and skin? I see that I am not the only one having issue with this because even the best articles I have read on OOCSS are inconsistent with one another. If this is going to be a standard of practice we need to agree on which items are skin and which are structure. If everyone is doing their own interpretation of OOCSS it loses its effectiveness. A final thought for me is that maybe I am not understanding the skin vs. structure well enough. If this is the case I welcome the correction.
