Gone Features a cool background slider. Setting it up is very easy. Every page can have its own background slider. Simply open the page you want to add a background slider to. Underneath the input field for the content of the page you will find a box called “Page Extra”. Here you can upload your background images (“Page Extra” not showing? On the top right of the page – click “Screen Options” – check “Page Extras”)
There is also an option to add a default background image. Go to “Appearance-Theme options” Scroll downs a bit and you’ll find a field to upload a background image. Alternatively you can also chose to show a background pattern by checking on of the boxes under “Background Option”. Make sure to click on the save button for the changes to take effect.
