Thanks for your help, I set the width attribute to 100%, something I didn't think of previously. I understood the need for javascript however, and for those interested this is what I wanted to make, I did so in a couple of hours panning through why it wouldn't work in Firefox, then it would work in IE etc.

timer = setInterval('showDateTime()', 1000);

document.getElementById('timeDate').innerHTML = date.toString();
clearInterval(timer);
timer = setInterval('showDateTime()', 1000);

Thanks a lot! Now the only issue I am having is the status bar's height gradually decreases when the browser window has shrunk vertically, but I'm sure I don't care

!

Now all I need is an idea to use it with.
