Thanks for writing in! Regretfully there is no available demo content for you to start with that looks like the X theme site, https://theme.co/x/. This is our sales page and if you want to replicate the design, you will probably start from scratch. Most users would use the Integrity 1 demo and start editing from there. You can also select our other standard demo contents or make use of our expanded demo contents. To know more about our demos, please check this out:
If you need to know how to figure out the banner slider, please check this detailed instructions:

Hope this helps.
