If you mean your biographies then its really a matter of personal taste. My bio layouts evolved over time as has most peoples due to how long we have been on base. Others have formatting they paid using in game currency (kumi which you will earn as you start battling and doing missions) which sadly selling bio layouts isnt a thing you can get paid for anymore. So its fair to see other bios look intimidating, especially when your newer to the forum.
While there arent any specific tutorials to my knowledge, a lot of it is just messing around with coding and finding out that way, looking at others bios can be a great source of inspiration. Im not sure how helpful this is, but give it time, if you want, if you go to the Konoha Town subforum you can create a thread in there and call it your workshop. And then that can be a dedicated space for you to try out different formatting.
For biographies, you can have a max of two (1 NW bio and 1 spare) until you rank up to Jonin where you can have 3 (1NW bio and 2 spare)
