@Kindbodesign: Generally we don’t recommend changing Font size and line spacing in responsive design site. You can change as per you need and add the following css in “Appearance => Theme Options => Custom CSS” box.
@media screen and (min-width: 961px) {
body,
button,
input,
select,
textarea {
font-size: 14px;
}
.entry-header .entry-title,
#homepage-message {
font-size: 30px;
}
article.sticky .featured-sticky, .page-header, p, .featured-image, .entry-content table, .comment-content table, .widget.widget_catcheverest_social_widget, #content .searchform, .page-link, .single-attachment .entry-attachment img {
margin-bottom: 40px;
}
}
