How do I locate and style my bootstrap link button under my navbar?

I'm fairly decent with .css but am struggling with how to access and style (re-style) my bootstrap link button under my navbar, once the navbar collapses. Below are some screenshots that should be helpful. I just need to know how to "grab" (get a hold of / select) my bootstrap link button so that when the navbar collapses I can change the padding on it. The pictures will show why I want to do this. Once the navbar collapses, the bootstrap link button is slightly off a bit. 8px to be exact.

Use the "Inspect Element" tool (first icon on the dev tools menu bar, all the way to the right, looks like a magnifying glass) and select the element you want to target.  If you still can't figure out how to target the element with CSS, post a screenshot similar to the ones you have now, but focusing on the lineage (ancestors) of that element.

You can just give it an id and then use this id to set its rules... But the best things would be make the logout link part of the list, as it should be normal. Unless you have some valid reason to keep the logout button outside the navbar-right, make it the last element of the list definitely fixes your issue. And this would be the correct way to do it.

You can use class .btn and .btn-link in your css and re-style it as you you want if you want a new default look for all other buttons (make sure to place it after the bootstrap.css).

Otherwise use the id and I also recommend to put the button as last <li> elemement in your <ul> list.
