Blue Border on Accordion Header when active

Hello,

I can't seem to get the blue border to disappear from the accordion headers when they are active:

Historic

In accordion Options under the Custom CSS tab, I edited as instructed:
#accordions-79{outline: none;}
#accordions-79 .accordions-head{outline: none !}
#accordions-79 .accordion-content{}

I'm sure I'm doing something wrong, can you help me out?

Thanks so much, I really appreciate it!
