You shouldn’t create multi custom post type, Think your project scope clearly.For Tutorials like html,css, js or other tutorials, you should create only tutorials custom post type. So that
yourdomain.com/tutorials
yourdomain.com/tutorials/html/
yourdomain.com/tutorials/js
It’s more readable and good for SEO. Analyze the project flow clearly and then you could configure well for that. Good luck in codes 🙂
