How I create a button system like (in image)

Hello! I'm trying create a Navigation Button like https://pokemon.fandom.com/wiki/Pok%C3%A9mon_Wiki does, but I tried do it but looks horrible. Someone can help me?

What I did:

What is supposed like:

Which "navigation buttons" are you talking about. I am seeing at least 2 things someone might call a "navigation button".
Have you tried starting by looking at what the other wiki has? And by this, I mean the actual markup not just the finished visual product.

Hello, the buttons where it says "Characteres" "Pokedex " "Locations" (...)

I tried do it, but went wrong. I need help

What do you think?
