Flush Images in Header?

Hi,

I’m trying to create a menu bar in the header so I have graphical menu buttons. On ly problem is, there is a gap betweeen the images. It looks like there’s someplace in the code where padding has been added, but I can’t find it. I’d love for the images to abut the image above and each other. Here’s the link if anyone wants to see what I’m talking about: https://phyzica.com/blog/wordpress/

Thanks in advance to anyone who cares to try and help me out.

Best wishes,
Shawn

ps- I originally put this in the Installation section by accident
