Bootstrap
The most popular HTML, CSS, and JavaScript framework for developing responsive, mobile first projects on the web.
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.

Project mention: How to use Angular 20 experimental Vitest support outside of ng test | dev.to | 2025-06-18
So, I had to test this new version in a personal project to learn how to use all these new things along with other technologies and tools I’ve used for a long time and also love, like VSCode, ESLint, Prettier, and a bunch of other. And I did, but there’s a catch which makes the whole “experimental” thing have more sense: you can only use this through ng test.
