To set the font for the content go to Appearance > Customize > Typography.
Or If you need to set manually just go to Appearance > Customize > Additional CSS. and paste the below custom CSS code.

@media (min-width: 768px) {
	body,
	input,
	textarea,
	select,
	blockquote footer,
	.blockquote-footer,
	blockquote cite,
	.form-control,
	input,
	textarea,
	select,
	.site-description,
	.search-block .form-control,
	.wp-block-image,
	.wp-block-image figcaption,
	#bbpress-forums,
	#bbpress-forums button,
	#bbpress-forums ul.bbp-lead-topic,
	#bbpress-forums ul.bbp-topics,
	#bbpress-forums ul.bbp-forums,
	#bbpress-forums ul.bbp-replies,
	#bbpress-forums ul.bbp-search-results,
	div.bbp-search-form input,
	div.bbp-search-form button,
	div.bbp-breadcrumb,
	div.bbp-topic-tags {
		font-size: 15px;
	}
	th {
		font-size: calc(15px + 3px);
	}
	.site-footer .widget-area .newscard-widget-recent-posts .post-boxed .entry-title {
		font-size: calc(15px + 1px);
