Primary: The primary button is the main call to action for the user, guiding them to next steps in common workflows or recommended actions. There should only be one primary button per page.
Secondary: Secondary buttons typically accompany a primary CTA on a page, or they may stand alone to offer optional actions. Often paired with primary buttons.
Transparent: Transparent buttons offer access to noncritical functionality that the user may need infrequently. Often paired with tertiary buttons.
Danger: Danger buttons alert users to potentially consequential actions
Danger Transparent: The danger transparent button is used to be a subtle alert for consequential actions
Button Group: Button groups are used to group related options. To emphasize the ability to toggle between options, a button group should be housed in a common container.

Buttons are used primarily for actions, such as “Add”, “Close”, “Cancel”, or “Save”. Plain buttons, which look similar to links, are used for less important or less commonly used actions, such as “view shipping settings”.
For navigational actions that appear within or directly following a sentence, use the link pattern. Links are used primarily for navigation, and usually appear within or directly following a sentence.
Button groups are used to group related actions, not as an element for navigation between different types of data. Consider tabs for this type of interaction.
Button groups provide higher visibility while dropdowns save space, so consider users' needs for the context.
Use a button group with a dropdown button when you want to group a default action with several variations of that same action.

Button labels should be clear and concise--one or two words maximum in most cases. Users shouldn’t be surprised by what happens when they click a button.
Labels should be action-oriented, including a verb that can be paired with a noun for clarity. Common actions like “Close”, “Save”, or “Delete” may not always require a clarifying noun.
Use sentence case and don't include any punctuation.
