About Viewport Tag Checker

The Viewport Meta Tag Checker is an essential tool for modern web development. It scans your website to find and validate the `<meta name="viewport">` tag, which controls how your site is displayed on mobile devices. Without a correct viewport tag, mobile browsers will render your site like a desktop page and shrink it down, making text unreadable. This tool ensures you have the standard configuration (`width=device-width, initial-scale=1`) set up correctly.
