To be more clear, I've tried creating two new tiddlers (HTMLStart and HTMLEnd), one for the HTML before the body and one for the HTML after the body. I've tagged these with $:/tags/ViewTemplate, then I rearranged them so the do surround the tiddly body. But it doesn't like that they are HTML. If I open and close a DIV in the HTMLStart tiddler, then it will display correctly on every tiddler. Same goes for the HTMLEnd tiddler. But if I open a tag in the HTMLStart tiddler and try to close it in the HTMLEnd, it doesn't work correctly.
