We'll create fresh WordPress site with COVID-19 Float Button installed. You have 20 minutes to test the plugin after that site we'll be deleted.
This plugin creates a floating button with a link to a read more page (which you have to create yourself), meant for COVID-19 information. You can choose from different icons and set the colors, text, link and position of the button (including offset) in the WordPress backend. It is aimed to be simple and lightweight.
