That looks like it would be outside of the whole site in the background on the right, correct? You would need to add the code somewhere in the footer.php file and then style it to appear where you want it on the right. Be aware, that people will not be able to see that on certain devices and screen sizes.

Thank you very much for the reply.

Yes exactly, outside of the whole site in the background (which we can change color of it Magazine Basic settings) and on the right side.

How can I style it to appear on the right? Is there any sources that I can learn how to do it?
Or is there a simple code that I can use and change?

You would need to create a container for your code and then use CSS to style it so that it appears outside of your main site. You will need to use the absolute positioning style so look into that.
