Want to delete author, leave a comment and change font for category

I have wordpress site with Pro theme called Cornerstone. I use Blog Designer Pro. Underneath a blog title I would like to delete the author and leave a comment, and change the font for all categories for blog posts to Bayshore (which I have loaded). On my blog’s main page https://divinestyle.co/blog/ I would like to get rid of the black coloring behind the category with the category font being larger and in the same Bayshore font which I have loaded. How can I change the font for blog categories to Bayshore on both blog posts and the main blog page?
