FAQs custom code

Hello I wanted to change the style of the FAQ page on my website FAQs — mentorship studio
This is as I want it to blend better to the format/style of my website.
Please could the below made possible?:
-Unbold all the text (I do not want the text bold)
-have the text all grey even when the question is clicked on to see the answer response.
-have grey text background on the answers disappear or turn white.
-any other way to make it blend more naturally with my website.

I think my YouTube Videos tab is a good guide for how I want the widget to look as I have the youtube gallery widget on that page! So if you can get it all to match and look seamless that would be amazing!

Many thanks!
