Navbar section links don't take to the beginning of section and the transitions are jumpy

Hello there,

I have a home page with sections. The nav bar is fixed (top), with links that point to sections on the home page.

The problem is that when I click on the link the page takes me to the section but not to the beginning but to vertically off by ~100-200px.

The last link (“Contactame”) is another issue. The transition doesn’t flow it is jumpy and have no idea of how to fix it.

Can anybody help please?
