How to customize my blog post

I am using Ultra Themify theme to create a Multi Author website.

I want to customize the blog post and the author page to make it look more fancy and presentable.

My Blog post : https://www.travelkathak.com/from-rags-to-riches-in-turkey-33/
How i want it to look : https://www.tripoto.com/trip/the-perfect-itinerary-for-gokarna-566ab204f1300

My Author Page : https://www.travelkathak.com/author/aditya-shroff/
How i want it to look : https://www.tripoto.com/profile/kirats

Kindly guide me how to go ahead with this.

Thanks and Best Regards,
