Personalize the badge by changing it's background color, text color, font size, and the length it stays visible. TailwindCSS developer bliss. ❤️ Updates v1.1.1 - Add the ability to create custom breakpoints. - Fix an annoying issue where you couldn't interact with the website canvas where the breakpoint pill was.
