Child Theme style.css doesn't overwrite BusinessSerivces parent css

So, I am trying to get my child theme *.css file to overwrite the parent *.css file for Buisness Services.

I am new to code and am not sure what I am doing wrong. I can activate the child theme and edit the child theme, but the changes do not appear on the live website.

When I examine the code with firefox Inspect Element, I can see the parent *.css is called and the child *.css is called, but the child is crossed out and the it appears it is not taking effect.

I'm not sure how to enforce the *.css changes that I am typing into the child theme. Any help would be appreciated.

Specifically: evoc.underthelee.com

businessservices.css:136
and
style.css:31

(Trying to remove padding to tighten up the header image so there is 0 padding.)
