What does the viewport meta tag do?

It tells the browser how to scale and size the page on mobile devices. Without it, most mobile browsers render the page at a 980px desktop width and then scale the whole thing down, making text tiny and layouts broken on small screens.

What is the recommended default viewport tag?

For most responsive websites the standard tag is: . This sets the viewport width to the device screen width and loads the page at a 1:1 scale with no initial zoom.

Should I set user-scalable=no?

Disabling user-scalable is generally discouraged for accessibility reasons — users who need to zoom in to read content will be unable to do so. Only use it for full-screen app experiences where zooming would break the UI. WCAG guidelines advise against blocking zoom for text content.

What does initial-scale=1.0 mean?

It sets the initial zoom level when the page first loads. A value of 1.0 means no zoom — one CSS pixel equals one device-independent pixel. Values less than 1 zoom out; values greater than 1 zoom in on load.

When would I use a fixed pixel width instead of device-width?

A fixed pixel width (e.g., width=480) is useful for pages designed for a specific device or screen size, such as kiosk displays or legacy mobile-only sites. For modern responsive design, always use device-width.

Do I need the viewport tag for desktop-only sites?

If your site is strictly desktop-only and will never be viewed on mobile, the tag is not strictly required. However, adding the standard tag does no harm and ensures the page behaves correctly if someone opens it on a tablet or phone.

Where do I add the viewport meta tag?

Place it inside the section of your HTML, ideally near the top before any stylesheets. In WordPress, most themes already include it; if not, add it to the header.php template inside the block. There should be only one viewport tag per page.
