custom header navigation has odd spacing [closed]

I’m not sure what’s causing the causation of your problem, but for some reason the <li> tags are not being added around the “portfolio” menu item, when you visit the blog page. Maybe you can see why in the custom header menu code?!

The <li> tags are what creates the spacing(padding-right) in between each menu item, so without them on the portfolio item, the blog menu item shifts to the left.
