Spinner Ready

Spinners are used to indicate users that their action is being processed. Duet’s spinner is built entirely with HTML and CSS, and doesn’t rely on JavaScript.

You can customize the size and color of the spinner with the provided properties. Spinner comes in three sizes: small, medium and large.

Examples #

Open in new window
<duet-spinner size="small" theme="default"></duet-spinner>
Open in new window
<duet-spinner size="medium" theme="default"></duet-spinner>
Open in new window
<duet-spinner size="large" theme="default"></duet-spinner>
Open in new window
<duet-spinner size="large" color="currentColor"></duet-spinner>
Open in new window
<duet-spinner size="large" color="success"></duet-spinner>

Properties #

Property Attribute Description Type Default
accessibleLabel accessible-label Adds accessible label for the spinner that is only shown for screen readers. string undefined
color color Color of the spinner, as a design token entered in camelCase or kebab-case. Example: "color-primary". This property can also be set to "currentColor" which forces the icon to use the CSS text color of parent element instead. Useful when you want to control the color in stylesheet instead. string "gray-lightest"
size size Size variation of the spinner. "large" | "medium" | "small" "small"
theme theme Theme of the spinner. When used this will override the color setting and use "primary" or "primary-turva" as the color depending on which theme is chosen. "" | "default" | "turva" ""
