Apply uploaded font to ALL elements of site

Site URL: https://gregorylassale.com

I uploaded a custom font to SS and managed to apply it to all headings and paragraphs, but a lot of elements are still not included i.e. all cover page text, all buttons, accordion tabs text, contact form text, etc.

Is there a quick way to apply the custom font to all site elements with CSS, or do I have to look up and target individually all those elements?

I really wish SS made uploaded fonts available via Site Styles...

Thanks  

All figured out. No help needed. Thx. 

Use this CSS

* {
	font-family: enter-your-custom-font-name !important;
}
