Can I override safely summary block title font?

Site URL: http://thetechnologyletter.com

Hello, I'd like to override in CSS the MINERVA-MODERN font styling of this summary block shown in the attached inspector screen shot. I'd like to change it to the normal summary block font, ANZIANO. Would I use a PAGE modification in CSS editor for that? Thank you.

Use this CSS

.summary-title-link {
	font-size: 30px !important;
	font-family: monospace !important;
}

replace font size, font family with what you want.
