How can one get the same exact margin & padding for an element in IE, FF, Chrome?
To be exact take a look at this URL with Chrome:

Please look at the section under "Last 5 Questions Posted". The margins for each
of the Member Thumbnail fotos with their Question in front of it are correct under
Chrome. But if you look at the same with FF or IE you will see that they display
the same items with about 10% more Height, thus rendering the display wrong.

So what CSS code does one need to use in these Tables to result in the same
exact Height for this section under all browsers?

Note: I used this CSS style code in row that holds each of the member Thumbnail fotos
with their Question:

style="margin: 0px; padding: 0px;"

it made things lil better, but still the Height is not exactly the same
across browsers.
