        <h5>Import via Module</h5>
        <pre v-code.script><code>
import Message from 'primevue/message';

</code></pre>

        <h5>Import via CDN</h5>
        <pre v-code><code>
&lt;script src="https://unpkg.com/primevue@^3/core/core.min.js"&gt;&lt;/script&gt;

</code></pre>

        <h5>Getting Started</h5>
        <p>Message component requires a content to display.</p>
        <pre v-code><code>
&lt;Message&gt;Welcome to PrimeVue&lt;/Message&gt;

</code></pre>

        <p>Multiple messages can be displayed using the standard v-for directive.</p>

        <pre v-code><code>
&lt;Message v-for="msg of messages" :severity="msg.severity" :key="msg.content"&gt;&#123;&#123;msg.content&#125;&#125;&lt;/Message&gt;

</code></pre>

        <pre v-code.script><code>
data() {
	return {
		messages: [
			{severity: 'info', content: 'Dynamic Info Message'},
			{severity: 'success', content: 'Dynamic Success Message'},
			{severity: 'warn', content: 'Dynamic Warning Message'}
		]
	}
}

</code></pre>

        <h5>Severities</h5>
        <p>There are four possible values for the severity of a message. Default one is "info".</p>

        <ul>
            <li>success</li>
            <li>info</li>
            <li>warn</li>
            <li>error</li>
        </ul>

        <h5>Closable</h5>
        <p>Messages are closable by default resulting in a close icon being displayed on top right corner. In order to disable closable messages, set <i>closable</i> to false.</p>
        <pre v-code><code>
&lt;Message severity="success" :closable="false"&gt;Order Submitted&lt;/Message&gt;

</code></pre>

        <h5>Sticky</h5>
        <p>
            Messages are sticky by default, if you require them to be cleared automatically, disable <i>sticky</i> property and optionally configure the <i>life</i> property to specify how long the message should be displayed which is 3000 ms by
            default.
        </p>
        <pre v-code><code>
&lt;Message severity="warn" :life="5000" :sticky="false"&gt;This message will hide in 5 seconds.&lt;/Message&gt;

</code></pre>

        <h5>Inline Message Component</h5>
        <pre v-code.script><code>
import InlineMessage from 'primevue/inlinemessage';

</code></pre>

        <p>InlineMessage component is useful in cases where a single message needs to be displayed related to an element such as forms. It has one property, <i>severity</i> of the message.</p>
        <pre v-code><code>
&lt;InputText placeholder="Username" class="p-invalid" /&gt;
&lt;InlineMessage&gt;Field is required&lt;/InlineMessage&gt;

</code></pre>

        <h5>Accessibility</h5>
        <h6>Screen Reader</h6>
        <p>
            Message components use <i>alert</i> role that implicitly defines <i>aria-live</i> as "assertive" and <i>aria-atomic</i> as "true". Since any attribute is passed to the root element, attributes like <i>aria-labelledby</i> and
            <i>aria-label</i> can optionally be used as well.
        </p>

        <p>
            Close element is a <i>button</i> with an <i>aria-label</i> that refers to the <i>aria.close</i> property of the <router-link to="/locale">locale</router-link> API by default, you may use <i>closeButtonProps</i> to customize the element
            and override the default <i>aria-label</i>.
