Your home page is set to display the content like slideshow, image, text, blog content and so on using Gantry layout manager. The Layout Manager in the Gantry-based theme administration interface provides several options for setting up the layout of the theme's Outlines.
You can change the content by editing the Home Layout settings in the Layout manager in your site template administrator. Go to System -> Site Template Styles -> here you can see the Home layout style, i.e Veno Pro - Home (Template Name - Layout Name).
The layout(Home in this case) consists of several different sections, particles, each with its own set of settings that enable you to customize the behavior and look of your site on the front end.
