Install issues - Install Path vs. Web root directory vs. Server-Document Root

[cmo]

Ok, I shut down my browsers, reopened, cleared my cache, cookies, etc..

Navigated to the localhost/Reservations/ and am now getting the home page. The body content is tucked up under the navbar at the top. CSS issue?

I click on any link and the page is not found.

Here is the url in the Admin link:
http://localhost/users/account.php

You can see the this should be: http://localhost/Reservations/users/account.php

the 'Reservations' is missing in all the links.

Help.
