Why is there a one pixel gap created between the top and the bottom of the p tag in the following code in IE6 and IE7 but not in Firefox or IE8? I have been pulling my hair trying to create the search texbox on powerset website and interesting enough they don't have the bug in IE6 or IE7. What am I doing wrong?
