Hooking bootstrap is pretty easy and gives you an awesome result. The only part that is tricky is the navigation, fortunately smarter people than myself have already figured this out. I suggest you take a look at this tutorial on using bootstrap navs with WP:
Integrating bootstrap and Worpdress menus
The only problem with these tutorials is they assume you are going to drop the nav_walker file into theme home directory. What happens when you want to place it in another folder? Personally I like to put all my bootstrap files in their own folder. After tinkering around with this for a while I come up with this line:
[dt_code]// Register Bootstrap Navigation Walker
include_once (‘inc/bootstrap/wp_bootstrap_navwalker.php’);[/dt_code]
In my example you would be placing the walker inside the bootstrap folder which is inside the inc folder. Happy bootstrapping!
