Responsive Faq Accordion Card using SASS with partials/vanillaJS

Hi guys,

Appreciate any feedback, especially on the following:

• the way I wrote my JS. I'm not sure if that is the right way, but since certain elements needed to be changed while others not, I made use of an array and filtered it as well in order to apply classes to certain elements only. Is this the right way? or is it too work-intensive?

• I'm getting an issue when checking the accessibility in the browser devtools. "Clickable events must be focusable and should have interactive semantics" The arrow icon is inside an my button though. How do I fix this?

• HTML5 markup, especially from an accessibility stand point. I feel like I need to still work on that a lot.
