You can have multiple self-closing meta elements on a web page. Each meta element adds information about the page that cannot be expressed by other HTML elements.
Add another self-closing meta element within the head. Give it a name attribute set to viewport and a content attribute set to width=device-width, initial-scale=1.0 so your page looks the same on all devices.
