Question

This is my jsfiddle:
http://jsfiddle.net/BTYA7/4/

At the bottom of the white input box we can see that there is about 5px of padding / margin between the border and the white box. I have tried to use chrome developer tools but I cant see where it is coming from, can anyone help me pinpoint it?

It seems to be on this:

<div class="uEditor" style="">

But in the metric window there is no padding

Answer 1

That is because of the line-height property .. Set it to 0

.uEditor
{
    line-height: 0;
}
