mobile menu presentation

Hello there,
I am trying to fix the custom css for the mobile version of my header. I attempted to add margin to the mobile menu button in order to create space however that has not worked. I see that from how it looks in the preview on the backend in comparison to a visitors view is completely different and does not show the logo or header button menu as well.

I appreciate your help.
