[jQuery] span tag is width:80px but is only showing the width of contents?


Hello,
I've got a SPAN tag which is set to 80px...
<span style="width:80px; background-color:#00FF00;">A</span>
The contents of the SPAN is a single character and when rendered on
screen, the green SPAN is showing as only approx 15 pixels in width.
How can I force the width to be 80px?
Thanks,
Nick
