Hi.,
1 ) Our theme contains full dummy content except the images Because of images used in the demo are not included for download, these images are copyrighted. If you are planning to use the photos we can provide the links to buy license.
2 ) Sorry , you can’t directly preview the header and footer .
3 ) Sorry , as of now we don’t have that option . We are working on that update we will add this feature in our next update .
