Tailwind Viewport Sizer is a Chrome extension that offers real-time insight into your current viewport size and includes Tailwind CSS breakpoint names like sm, md, lg, etc. This handy tool allows you to set the viewport size using the simple popup feature.

With Tailwind Viewport Sizer, you get a beautiful badge that displays the viewport size and fades away after a few seconds, ensuring you are designing for the correct devices. It's a great way to personalize the badge with options to change its background color, text color, font size, and duration of visibility, providing TailwindCSS developers with a delightful experience.
