I want to reduce the width percentage on the #Top_bar .menu > li > a:after line to 50% but I can't find a way to center it once it's reduced.  This is my current style.  What would you recommend I do?
This is for

#Top_bar .menu > li > a:after { 
content: ""; 
height: 2px; 
width: 50%; 
text-align:center;
position: absolute; 
left: 0; 
top: 64px; 
z-index: 203; 
opacity: 0; 
filter: alpha(opacity=0); }
I appreciate your help.
Thank you
Erik

but as we see, this line is already 50% width http://snag.gy/j0zW3.jpg so we don't understand what else you want to do.
Thanks!
#Top_bar .menu > li > a::after { left: 25% !important; }
