Typography changes

Is there anyway I can figure out which Heading tag corresponds to items on my site.
Foe example, I am trying to change the font size of my menu. When I change typography/Heading nothing happens.

Dear Dedra,

So you want to change the font size of the page heading? For instance, “HEY I WAS THERE TOO” text on “About” page http://dedrashores.com/about/. Please advise.

Yes as well as my menu and sidebar fonts.

To change the font size of your page heading, edit the respective “SiteOrigin Headline” widget > Widget Styles > Attributes > in the “Widget Class” field, enter: page-heading.

Then apply the following CSS code through the Simple Custom CSS plugin or child theme’s style.css.


.page-heading h3{
  font-size: 20px;
}

To change the sidebar widget font heading, add this code:


.widget-area .widget-title{
  font-size: 20px;
}
