Your web page is not rendering correctly on mobile devices. What elements and attributes within the head section can you use or modify to ensure proper rendering?

The viewport meta tag ensures that the page width is set to the screen width of the device and the content is rendered with an initial zoom level of 1.0. This is essential for responsive web design and ensures that pages render correctly on a variety of devices, especially mobile phones. Other options don't directly address rendering issues specifically in the head section for mobile devices.
