I'm working on my first epub, and I would like to use the following CSS scheme:

1. Most paragraph tags would have no class assigned and would be styled by a simple rule in the style sheet...

```
p {}

```
2. A special series of paragraph tags would have a different style. However, I would put these paragraphs inside div's, so the style would just look something like this:

```
div.footnote p { margin: 2px 15px; indent: 0; }

```
3. Any remaining paragraphs that require special styling would be assigned classes. They would be the **only** paragraph tags with classes.

Is this scheme OK, or is there a special reason I should give **every** paragraph tag a class? I'm asking because I think I remember a comment about this on some tutorial that I can't locate right now. I just want to make sure I'm not making a major gaffe by creating an epub with empty tags.
