        <h4>Icons</h4>
        <p>Babylon uses PrimeIcons v6, PrimeTek's new modern icon library.</p>

        <h5>Getting Started</h5>
        <p>PrimeIcons use the <strong>pi pi-{icon}</strong> syntax such as <strong>pi pi-check</strong>. A standalone icon can be displayed using an element like <i>i</i> or <i>span</i>.</p>
        <pre v-code><code>
&lt;i class="pi pi-check"&gt;&lt;/i&gt;
&lt;i class="pi pi-times"&gt;&lt;/i&gt;

</code></pre>

        <i class="pi pi-check" style="margin-right: 0.5rem"></i>
        <i class="pi pi-times"></i>

        <h5>Component Icons</h5>
        <p>Components that have icon properties accept PrimeIcons with the <strong>pi pi-{icon}</strong> syntax.</p>
        <pre v-code><code>
&lt;Button label="Confirm" icon="pi pi-check"&gt;&lt;/Button&gt;

</code></pre>

        <Button label="Confirm" icon="pi pi-check"></Button>

        <h5>Size</h5>
        <p>Size of the icons can easily be changed using font-size property.</p>

        <pre v-code><code>
&lt;i class="pi pi-check"&gt;&lt;/i&gt;

</code></pre>

        <i class="pi pi-check"></i>

        <pre v-code><code>
&lt;i class="pi pi-check" style="font-size: 2rem"&gt;&lt;/i&gt;

</code></pre>

        <i class="pi pi-check" style="font-size: 2rem"></i>

        <h5>Spinning Animation</h5>
        <p>Special pi-spin class applies continuous rotation to an icon.</p>
        <pre v-code><code>
&lt;i class="pi pi-spin pi-spinner" style="font-size: 2rem"&gt;&lt;/i&gt;

</code></pre>

        <i class="pi pi-spin pi-spinner" style="font-size: 2rem"></i>

        <h5>List of Icons</h5>
        <p>Here is the current list of PrimeIcons, more icons are added periodically. You may also <a href="https://github.com/primefaces/primeicons/issues">request new icons</a> at the issue tracker.</p>
