I'm creating a book that includes horizontal rules (i.e. the <hr> tag). The rules are visible in my book but they are faint and I'd like to make them more noticeable.

I've tried adding the following to the style sheet:
hr {height: 10px;}
but the formating seems to be ignored.

So my question is: has anyone succeeded in formatting horizontal rules in a kindle book, and if so, how?

Thanks.
