The Home Template is used to automatically display the slide show on the top of the page, and the 3 columns on the bottom of the page.
The image below illustrates these features.
If we would open this page in the backend of WordPress, the body of the page would be blank. Because this page is using the Home Template, images that have been uploaded into the Image Gallery are displayed in the slide show.
Text can be added to the body of the edit screen. If text is added, it will appear between the slide show and 3 columns. The image below is an example of text added to the body of the home page.
The 3 columns on the bottom of the page is also automatically generated. The text for the columns is added/edited in the Appearance>>Widget area.
