What are next and previous buttons called?

Previous and next buttons are navigation buttons on a website, an app.

What is a ghost button?

Ghost buttons are transparent calls to action that appear on websites and in apps. They tend to have a thin border and a text label that sits within the transparent body of the button. The use of this type of button reached its peak a few years ago, but can still be seen across a wide range of websites.
