[Theme: Blaskan] How to modify font and color in child theme

I’m very new to WordPress, but I love the minimalist look of the Blaskan theme. I have uploaded and activated the most recent Blaskan child theme boilerplate and have attempted to edit the child theme’s stylesheet, but none of my style.css modifications are showing up. It’s as if the child theme isn’t overriding the parent theme for some reason. Specifically, I am attempting to change the font styles and sizes (headers and body), take off the uppercase text-transformations, and change link/button colors. Any suggestions for getting my child theme changes to show? Thanks in advance!
