when looking at the layout tab of the firebug inspection….i noticed the ‘-13’ at the bottom…where is it from? what does it mean? i did not specify it…why is it showing there? what does it tell me about ‘bottom’? or it means something else?

Answer 1

It’s show position from bottom in minus if the position from top overlap or more than his parent.

Check this example http://jsfiddle.net/wqrh6/

in this when .myElem position top overlap his parent then the firebug show position from bottom
