Custom <head> and <body> Code per Domain

Simply paste in any custom code you have here, and this will now appear on the frontend of the website in the respective sections. {% hint style="success" %} This is great for Google Analytics integration, or any other 3rd party tool that require custom code for each domain on your site. {% endhint %}
