That is the Image and Content Fader in the Custom 1 position. The majority of the demo content is widget-based, so most of what you'll probably want to change will be controlled by widgets; you'll also want to look through the theme options ("Shape 5 Theme" on the menu) for layout and color options.
Okay, thanks for your answer. I could do it after that.
Now, I have other questions:
1) I'm creating a new blank page, but by default it is appearing S5 Accordion Menu on the right side of my new page. How can I do to remove accordion menu?
Besides, "Testimonial" and "Stay Notified" section appeared at bottom too. Can I remove them of any way?
2) In the existent .../pages/contact-us there is a contact form at bottom. Where Can I modify it? And where Can I add it in other page?
Thanks for your collaboration.
