I noticed that I can add social networking buttons to the bottom of the home page. Is there a way to add them to each post?
There are no built in options for that other than one you can see in theme footer. However, you can use plugin such as Jetpack to achieve the same result we have on theme domo right below post content. You can see it here: https://colorlib.com/dazzling/template-sticky/
