Hi,
We have looked in this page and the problem seems to be related to the "Cambria Math" font your page used. In some of our test system, the following HTML:
Code: HTML/ASPX
<p style="font-family: 'Cambria Math'; font-size: 12pt;">abc</p>
Will have an extremely large ascend and descend value that results in a single line of the above text takes up 89 pixels in vertical direction. The ascend/descend values are defined in the font. If you change it to a different font, then the problem will go away.
Thanks!
