Attributes


JET Avatar

Description: Themeable, WAI-ARIA-compliant element that often represents a person.

A JET avatar is an icon capable of displaying a custom image, or initials, or a placeholder image. The order of precedence for what is displayed, in order from highest to lowest, is:

  1. Custom image specified through the "src" attribute
  2. Initials specified through the "initials" attribute
  3. Default placeholder image
//Avatar with initials
<oj-avatar initials="AB">
</oj-avatar>

Accessibility

To make the component accessible, the application must set the role attribute of oj-avatar to 'img' and provide a value for the aria-label attribute. JET Avatar does not have any interaction with the application, therefore it is not keyboard navigable by default. The aria-label will be picked up by the tabbable/focusable parent unless it is overriden by the application. The application can set a tooltip by setting the title attribute of the avatar. It is recommended that the title and aria-label attributes are in sync.

In order to meet accessibility requirements for text, color contrast ratio between the background color and text must be greater than 4.5 for the two smallest avatars and 3.1 for the five larger avatars. Avatar's default background satisfies the 3.1 color contrast ratio. The background will automatically be darkened for the two smallest sizes to satisfy the more stringent 4.5 contrast ratio. If colors are customized through theming, the application is responsible for specifying colors that satisfy the 3.1 contrast ratio. The custom background color will be automatically darkened as well for the two smallest avatars.

Image

The avatar will display the image provided from the src attribute if the src attribute is populated. If the src attribute is not provided and the initials have been, the initials will be displayed. If neither src nor initials attributes are populated, a single person placeholder image is shown. Use the class oj-avatar-group-image to use the group placeholder image. Examples displaying each type of avatar:

//Individual Placeholder
<oj-avatar>
 </oj-avatar>
//Group Placeholder
<oj-avatar class="oj-avatar-group-image">
 </oj-avatar>
//Initials
<oj-avatar initials="AB">
</oj-avatar>
//Image
<oj-avatar initials="AB" src="image.jpg">
</oj-avatar>
