Please take a look at the following image..
As you can see.. I have added \[code\]:hover\[/code\] property to the \[code\]div\[/code\] enclosing each comment. but I get a small white space. When I use the chrome dev tools to highlight elements, the white space comes out of the area of all elements. it seems its a white space stuck between two divs. Please help me remove it. I added \[code\]margin-top\[/code\] as a neg value but it gives a jerking effect on hover.
