OK, I'm stuck, and the problem is blockquote elements.
When I use blockquote, the blockquote elements wind up inside paragraph elements instead of surrounding them. I need to fix this so that my page will validate. How on earth can I do this?
Details:
I begin my blog entry and type 8 paragraphs of text. No tags yet. Then I put a set of blockquotes around 2 of those paragraphs. The blockquotes are the only HTML elements I've typed.
In MT I leave text formatting set to convert line breaks. (Because the only other option is none, and if I were to use that I'd have to type in my own paragraph tags all over the place; don't want to type paragraph tags.)
Preview looks ok. Then I publish the entry. It displays ok, but the source code shows the blockquote problem described above. And of course the page won't validate due to that problem.
So, any suggestions? I'll be a very happy camper if somebody can tell me how to get around this problem.
UPDATE: I tried the solution at Jeff Szymona's site:
use blockquotes and still validate but it didn't do the trick. I added the macro lines specified on that page... now I'm trying to figure out what the next step is. Template changes?
