I have done something less brilliant but no matter how much i check in Firebug, i can’t see any style that causes the buttons to get this weird margin on the left side. In fact, they don’t even flash (on mouse over) except at the leftmost edge.
The question is twofold. What did the evil computer did?
And, more importantly, how does one trace the source of this weird layout?
The demo page can be found here.
input[type="button"], input[type="submit"]has a left margin of 120px.
