What is a ghost button?

A 'Ghost button' is the name given to those buttons that have a label and an outline but no solid fill, where the body of the button adopts the look of the background. They are commonly used on websites and user interfaces with simple and minimalistic aesthetics.

Can there be 2 primary buttons?

Primary. Primary buttons are used for actions such as 'Submit', 'Continue', 'Finish', or 'Log in'. They enable the user to complete the most important action on the page. There should only ever be one primary button on a page.

What is a split button?

A split button is a hybrid between a button and a menu: it groups related commands together into a dropdown, but also offers one-click access to a default choice that doesn't require opening the menu.

How do you use a split button?

A split button has a default action followed by a divider line and an arrow. When the arrow is clicked it exposes a drop-down list of alternative actions. This pattern is used when there are many possible actions but only one primary action.
