I'm currently making a website with a complicated design. I use to play with Firebug to controle layers placement, to trace unwanted margins and so many strange html behaviors. But ... Internet Explorer is a crappy piece of program ! If Firefox make some strange things, Internet Explorer is doing really what it wants.
So I tried to find out an equivalent of Firebug for Internet Explorer. I know that Firebug exists as a javascript script, but I didn't want to change my code just for that.
