Guidelines / Usage

When to use

A button (<button>) element is used to indicate an action.

When not to use

If you are directing a user to a new location, consider using an anchor (<a>) element, which can also be styled like a button when actions and destinations are present in the same set of controls.

Do not use buttons as navigational elements. Instead, use links when the desired action is to take the user to a new page.

Types

Use categories to bring varying action emphasis that guide the user when performing tasks.

Button type	Use case
Primary Button	Most important action on the page/section. A layout should contain a single primary button that makes it clear that other buttons have less importance in the hierarchy.
Default Button / Secondary	Default Button for all other actions, that are available or less important than the primary
Ghost Button	For the tertiary actions, who are less important or could stick out to much.

Alignment

Buttons can be aligned left, right, or center depending on the context.

Alignment	Use case	Sample Picture
Left alignment	In page content and forms where the content is typically unconstrained other than by the normal OO Grid.
Right alignment	In fixed dialogs flows (Yes/No, Cancel,Delete...) that continue in a progressive direction (wizards) and toolbars.
centered	used for Emtpystates or when the content has the only available action on the screen.

Order

When using multiple buttons, the position of the primary action is the most important part.

A primary button will be left-aligned and positioned to the left of the secondary/tertiary button.
