Hi Courtney,
Sorry for the delay.
Built in theme options typography settings implemented to all headers.
To change the font size/family/color for individual H1, H2, H3… you have to set it via custom CSS.
First Go to Appearance -> Theme Options/Customize -> Webmaster Tools -> Analytics
and paste your font script in the header script box which is given by font integrate service such as Google Web Fonts
Now integrate the font into your CSS Go to Appearance -> Customize/Theme Options -> Design Options Tab -> Custom CSS paste the following CSS code and Click on save button:
h1 {
font-family: "Philosopher",sans-serif;
font-size: 30px;
line-height: normal;
color: #555;
}
Change above individual value with the one you want to set for h1 and repeat same for h2, h2, h3…..
Thank you!
