not sure if it will work but you can try reducing the width or shifting this code to the left,
ie:
#template_nav { position: relative; margin-top: 20px; left: 1em; width: 60%;} (google if not sure)
 
as compared to the original code:
#template_nav { margin-top: 20px; ; } not sure how it will play out *sorry, i havent coded in a long time on neo!* because the links that neopets uses are actually images, so i tend to see many people just make their own navigations and keep the original nav to display:none or visibility: hidden.
 
ohhh and also to identify the elements better and what code edits which part on the front end, i use a plug in tool on chrome! its called CSS viewer :) it even helps you to identify the colors and hex codes!
