How can I adjust font and image sizes in my Dawn template shop?

Store Design

Hello there,

I need some fixings for my shop…

  1. I want the info pages (like Impressum, about us, jobs…) to have a smaller font size.

  2. I want the category texts and headlines to be smaller (but without changing the headline/ menue text size!!)

  3. how can I change this page https://www.herzenspony-shop.de/pages/jobs into something like that?

https://www.spooks.de/jobs

(the slider picture should be that small also. I can only change the width for all pictures).

Thanks for helping me!
