Give your team's presentations a consistent typeface by loading a custom font in a theme. You can use fonts from Adobe Fonts (formerly Typekit), Google Fonts, or your own host. All of these options are available through the theme CSS editor.
Adobe Fonts and Google Fonts
Open the theme CSS editor and follow the steps in Custom fonts.
Import a font stylesheet
You can also load a font by importing a stylesheet that defines it, such as one from your own font host. This example imports the Comfortaa stylesheet from Google Fonts and applies the font to all headings:
@import url(https://fonts.googleapis.com/css?family=Comfortaa:400,300,700);
.slides h1, .slides h2, .slides h3 {
font-family: 'Comfortaa', sans-serif;
}
