This extension shows the current viewport size including the TailwindCSS size. You can also set the viewport size using the popup.

Tailwind Viewport Sizer is a handy extension designed to provide you with real-time insight on your current viewport size, including the Tailwind CSS breakpoint names (sm, md, lg, etc.).

A beautiful badge that fades after a few seconds let you know what the viewport size is, while you're resizing the browser window, to make sure you're building for the right devices.

Personalize the badge by changing it's background color, text color, font size, and the length it stays visible. TailwindCSS developer bliss. ❤️
