Setting max-height causing large text to show up in padding area

HI,
I am attaching an html file :
In this there are two entries... And the text part in each entry i have set max-height to be 60px..
In the first one as the height is < 60px the padding area which is empty area just under the text shows up.
whereas in the next entry since the height of text is more than 60px . The text is getting overlapped over the padding area.

How can i prevent this...I want to show max text of 60px in this area followed by the empty padding area no matter what the size of text is.

Thanks
