    Project mention: Have I Been Pwned 2.0 is Now Live | news.ycombinator.com | 2025-05-19

    Not in the so distant past, when Bootstrapped themes were becoming the face of the Internet, a new framework came to town — TailwindCSS. The smart thing they did was introduced the framework with a few brilliant template and a lot of styled components. I bought the initial copy and does a lot of people. Those templates, TailwindUI.com (now TailwindCSS.com/plus)[1] became the gradien-y, dark-ish, glow-y design you see a lot these days.

    A similar design wave is also happening with internal dashboard, admin interfaces. Thanks to https://ui.shadcn.com Personally, I'm fine with the standardization of such functional interface designs.

    btw, for Have I Been Pwned, this is Bootstrap[2] and I'm not surprised it is also inheriting those design styles.
