Add a custom font
On Google Fonts, choose a font and select Get font, Get embed code, then @import.
Copy the @import line and paste it as the first line of your widget’s custom CSS. Then use the copy-paste example on that widget’s documentation page to apply the font.
Replace the example import and font-family value with the ones Google Fonts provides for your chosen font. Keep a fallback such as sans-serif after the font name.
