I could use an opinion on my code

I was able to find a free flyout menu template online, which helped a lot.
However there are two things that need changing:

1. the container’s width is temporarily set at 1050 px to fit all of the menu selections

(I need it at 766 px)
Maybe it could somehow recognize how much long each items name is and adjust the size of the menu accordingly (especially for “Home”)

2. I also need all the items in the dropdown menu to appear, and not get cut off due to their long name.

Here's a link to the CSS: http://students.uwsp.edu/rmarq423/site/menu_style.css
