Button component renders a native button element that implicitly includes any passed prop. Text to describe the button is defined with the aria-label prop, if not present label prop is used as the value. If the button is icon only or custom templating is used, it is recommended to use aria-label so that screen readers would be able to read the element properly.
<Button icon="pi pi-check" aria-label="Submit" />
<Button icon="pi pi-check" label="Submit" />
<Button class="youtube p-0" aria-label="Youtube">
<i class="pi pi-youtube px-2"></i>
<span class="px-4">Youtube</span>
</Button>
