If you keep the blank space at the top (margin-top) modest there will be little issue with user changes in the font size.
I commonly do this for each chapter using the following CSS:
Code:
h2 {
text-align: center;
margin-top: 4em;
margin-bottom: 0em;
}
where the chapter title is set as an H2 heading and often followed by a thin ornament:
Code:
<h2 id="heading_id_2">CHAPTER I</h2>
<p class="center">
<img alt="" height="34" src="../Images/Ornament19-211x34.gif" width="211" />
</p>
