I'm currently doing a school project and it would look better if I had defined a template and then used this to make my other pages, is there a way I could have done this without just coping and pasting the same page (which is what I did).
Basically, you would create your template page(s) and then use those as your base pages to create the rest so in a sense, yes and no. You need to create the templates yourself. There's really no simpler way to do this, even if you had some type of template system in place, you'd have to click the same amount of times so it's just as simple to make your own.
Be sure to use the Linking system so that your pages are easier to manage as well. Have fun!
