Native browser features are making JavaScript dependency stacks obsolete. The Popover API, the <dialog> HTML element, CSS nesting, cascade layers, the <details> element with its name attribute, color-mix(), :has(), and the ::backdrop pseudo-element are all now supported across Chromium, WebKit, and Gecko. Libraries like Floating UI, Tippy.js, Bootstrap Accordion, and React Tooltip solve problems the platform already solves.
The argument here is not nostalgia. The author built custom div components in IE6 just to get border-radius working. That context matters, because it shows why JS-heavy dependency culture existed and why it no longer has the same justification. Browser convergence and the accelerating pace of platform feature adoption have closed the gap that once made these libraries necessary.
The full article walks through specific replacements, feature by feature, with MDN references and real library names. Worth reading in full for the CSS syntax section alone, which covers relative colors, new math functions like pow() and sign(), and how these reduce or eliminate the need for Sass and runtime CSS-in-JS. The browser support caveats are honest and practical, not dismissive.
