My code works perfectly on my computer, on all my browsers (including ie), But I can’t manage to make it work on jsFiddle.
The problem seems to be on:
window.onload=function(){
document.body.innerHTML+=brd+log;
}
But I have tried both with and without the window.onload. I am totally clueless and I am starting to lose all hope
CSS (optional):
*{margin:0;padding:0;}
#brd{margin:15px auto;}
#brd,#brd td,#log{border:1px solid #000;}
#brd td{height:47px;width:45px;text-align:center;font-size:30px;}
#brd span{font-size:12px;}
#log{margin:15px auto;padding:20px;width:385px;max-height:150px;overflow:auto;background:#F0F0F0;color:#000;}
JavaScript:

It works ok, see here
PS: You should select the
no wrap (head)option.
