Hi,
I apologize if it's wrong place to put my question.
I decided to tweak some mobi books but my knowledge of html is sadly lacking. Could somebody please enlighten me:

<p height="0em" width="0pt"> why not simple </br> ?

or <a></a> - why? An empty anchor?

<a></a><p height="1em" width="5em"> seems to be put randomly before paragraph tags.
I know what happens when I change p-s to <p height="0em" width="2em">, but that's all.

Can I delete all <a></a>-s? Can I replace <p height...> tag to simple <p> (I think Mobi Creator takes care of indents)? (Well, I know that I can, but does it affect future conversion or readability in other readers etc?)

Most important, WHY <p height...> if <p> or </br> is sufficient?

Thank you.
