Create a page template to use over

Please pardon my newbe… I’m sure there is a way but it’s not obvious to me. I need to create a website that will have certain components on every page but the main content will change. How can I develop my page layout with those recurring components and save it to copy for the next page? Then I will only need to change the content for the next page.
And the big question is can I save it in such a way that if in the future one of those components change that I can go to one place to make that change and have it change across the entire website? Or will I be forced to make the change one page at a time?
Thanks for your help

Partials is your friend. watch this video to understand just how cool these can be. Especially with Foundry.


Thanks Steve! That is exactly what I was looking for.
