You can change the font by means of an Advanced typography option, which allows you to choose the item from a drop-down or insert your custom CSS class to avoid changing the font in the footer. Please navigate to the Theme Settings > Typography > Advanced Typography.
Thank you very much for choosing our theme and for contacting us.
WPBakery Page Builder and Revolution slider come bundled with our theme but they can’t be activated with our purchase code. Actually, you don’t need to do this. Only in case you want to get free premium support from its author, you can purchase it from Codecanyon. But it is not necessary since we will always provide you with the latest updates.
