Button custom class not being applied to hover?

Hi, I’m building out my first project, it’s a single page affair with a navbar that will scroll to various points on the page.

I’ve added a regular nav bric (bloc?), removed the navigation element and added a content area. Into this content area I’ve added my buttons. To the bottons I’ve added a custom class to change the padding and add some margin. All is working except the class isn’t being applied to the hover state, so when hovered, the buttons are all moving around.

How do I apply the custom class to hover?

EDIT: Ingore this. I’ve made life too hard: Just watched a video and discovered you can click Menu manager and set everything up from within there. Far easier. Sorted!
