Image slideshow interference with google font

Hi everyone, I’ve “completed” my tribute page but there are a few things I couldn’t accomplish that I wanted.

I wanted a font more suited to the arts as my tribute was for a historical cabinet maker. I imported a google font that I like to html but later implemented a slideshow through W3.CSS in the html stylesheet. This order of precedence overrode my font choice with the slideshow . At this point I found a method to import my font with CSS which works for my paragraph options perfectly but my h1 h2 elements lose their borderspacing when implemented.

I feel this is likely a simple error I’m overlooking and I appreciate any help.
