Deep study on K2 theme;

1. Entrypoint page index.php;

From the index.php, we can clearly see that it breaks the page intothree parts: header part; content part and footer part.

As for the header part, it use get_header() function to get thecontents.In the main content, it also contains two parts: primaryparts and sidebar part.There are three elements : notices, dynamiccontent and main content in the primary area. For the sidebar area,it also use the get_sidebar() function to fetch the relatedcontent.

Following the standard, get_footer() method is used to render thefooter's content.

2.Let me tell the stroy about get_header()

get_header() method can accept one paramter $name which providesone way to customize the default header page.When you pass the$name to get_header() method, it will use header-$name.php templateinstead of header.php.

There is another thing which need to be emphasized. It invokes theget_header action.By search, we can know clearly the methods whichbind to this action.
