Galleria uses <i>region</i> role and since any attribute is passed to the main container element, attributes such as <i>aria-label</i> and <i>aria-roledescription</i> can be used as well. The slides container has
|
||
|
|
<i>aria-live</i> attribute set as "polite" if galleria is not in autoplay mode, otherwise "off" would be the value in autoplay.
|
||
|
|
</p>

A slide has a <i>group</i> role with an aria-label that refers to the <i>aria.slideNumber</i> property of the <NuxtLink to="/configuration/#locale">locale</NuxtLink> API. Similarly <i>aria.slide</i> is used as the
|
||
|
|
<i>aria-roledescription</i> of the item. Inactive slides are hidden from the readers with <i>aria-hidden</i>.
|
||
|
|
</p>
|
||
|
|
|
||

|
<p>
|
||
|
|
Next and Previous navigators are button elements with <i>aria-label</i> attributes referring to the <i>aria.prevPageLabel</i> and <i>aria.nextPageLabel</i> properties of the <NuxtLink to="/configuration/#locale">locale</NuxtLink> API by
|
||
|
|
default respectively, you may still use your own aria roles and attributes as any valid attribute is passed to the button elements implicitly by using <i>nextButtonProps</i> and <i>prevButtonProps</i>.
|
||
|
|
</p>

Quick navigation elements and thumnbails follow the tab pattern. They are placed inside an element with a <i>tablist</i> role whereas each item has a <i>tab</i> role with <i>aria-selected</i> and <i>aria-controls</i> attributes. The
|
||
|
|
<i>aria-label</i> attribute of a quick navigation item refers to the <i>aria.pageLabel</i> of the <NuxtLink to="/configuration/#locale">locale</NuxtLink> API. Current page is marked with <i>aria-current</i>.
|
||
|

In full screen mode, modal element uses <i>dialog</i> role with <i>aria-modal</i> enabled. The close button retrieves <i>aria-label</i> from the <i>aria.close</i> property of the
|
||
|
|
<NuxtLink to="/configuration/#locale">locale</NuxtLink> API.
