            PrimeVue uses the <i>system</i> as the default <i>darkModeSelector</i> in theme configuration. If you have a dark mode switch in your application, set the <i>darkModeSelector</i> to the selector you utilize such as <i>.my-app-dark</i> so
            that PrimeVue can fit in seamlessly with your light-dark toggle.
        </p>

        <p>
            Following is a very basic example implementation of a dark mode switch, you may extend it further by involving <i>prefers-color-scheme</i> to retrieve it from the system initially and use <i>localStorage</i> to make it stateful. See this
            <a href="https://dev.to/abbeyperini/dark-mode-toggle-and-prefers-color-scheme-4f3m" target="_blank" rel="noopener noreferrer">article</a> for more information.

        <p>In case you prefer to use dark mode all the time, apply the <i>darkModeSelector</i> initially and never change it.</p>
