How do I migrate a site into WordPress?

Solution:

You do not need to convert anything if you have the files(js and css). Short story to move that into wordpress. Create a new theme, use Enqueue to enque your scripts from functions.php(you can do it from header.php too, but it’s not best practice and it will work slower). You can take a look at this. http://codex.wordpress.org/Function_Reference/wp_enqueue_script and at this http://codex.wordpress.org/Theme_Development for how to create a theme and how should it look.

For home.php or index.php you’ll need a simple query with a counter. The counter is for the css id(item1, item2, etc).
