Hi Ramon. It depends on what your choice is. With Gridsome they are starters you can choose from and in no time you have a blog running.
But you'll still need to know how to find your way around the code if and when you need to customize it to fit your needs.
Shameless Plug: I made a starter and I think it'll suit you if you want to create a blog with minimal design. gridsome.org/starters/minimal-starter
We're a place where coders share, stay up-to-date and grow their careers.
We strive for transparency and don't collect excess data.
