+        <p>Server-Side Rendering: Without Declarative Shadow DOM, servers cannot deliver complete websites that include web component content. Markup cannot be efficiently delivered and then hydrated with JavaScript client-side.</p>
+        <p>JavaScript-less environments: Many web components could be implemented without JavaScript, taking advantage of encapsulated DOM and styles. However, web components cannot currently be rendered by users who have JavaScript disabled. Developers who are more comfortable with markup than with scripting may avoid shadow DOM altogether due to its tight coupling with JavaScript..</p>
