Button Ready

Buttons are used for interface actions. They default to appearance that has dark text with gray border. Primary style should be used only once per view for main call-to-action.

Users generally expect buttons to submit data or take action, and for links to navigate. If navigation is required for the button, use the url prop. The control will then output an anchor styled as a button, instead of an HTML button.

Name	Purpose
`default`	Default style is the most common button variation. Only switch to another variation if you need to adjust the visual weight of the element. Please note that the default style uses transparent background so that it works nicely on Duet’s light background gradients.
`primary`	Primary style is reserved for the view’s main call-to-action. Should be used only once per view, e.g. for a submit action at the end of a form. This style also works on top of dark background or images.
`secondary`	Secondary style should be used for secondary actions in a view. Most commonly used when there is already a primary action and we want to highlight another action with a different style.
`negative`	Negative style is meant for dark backgrounds and to be used on top of illustrations.
`destructive`	Destructive style should be used for actions that delete data or otherwise make it hard to revert the action.
`plain`	Used for less important or less common actions.
`disabled`	Used for actions that aren’t currently available or not available anymore.
`loading`	Used to indicate progress when a button has been pressed and the action is still processing.
