Although we do provide a list of fonts for you to choose for your widget, you might happen to need a custom code.
If that is the case, add the code below to Custom CSS field on your Click to Call widget’s Appearance tab:
.global-styles, [class*="Main__Component-sc"] {
font-family: Lato;
}
You’re welcome to set any other font, providing it is supported by your browser and added to your website.
