website links

Hi there all

Having a small issue with the current link item on the custom pages that I am creating.

When I click a link it highlights which link I am clicking but it does not indicate the current page item by the border stroke I gave the active links.

When I click through to the sample page of wordpress it shows the current page I am on and it is highlighted with the border stroke I am using in the css.

When I hover over a link it also stretches the navigation div and causes the entire page to shift down until I remove the mouse from the link on the custom page. This does not happen on the sample page that wordpress has.

Please help.

Thanks in advance
