The CSS contrast-color() function returns black or white text for whatever background color a user picks. How the syntax works, why the @supports fallback still matters, and the cases it does not cover.
Streaming interfaces jump around and drag the scrollbar back to the bottom. What fixes it: tracking whether the user scrolled away, batching renders into the animation frame, and marking the container up as an ARIA log region.
The ::nth-letter selector still is not in any browser, and hand-wrapping every character in a span wrecks the DOM. A shim that rewrites the raw CSS into :nth-child and lets SplitText handle the markup and the ARIA.
Recruiters now expect designers to ship production code out of AI agents. Here is what that costs in practice: toggles no screen reader can see, XSS holes in generated forms, duplicated code, and engineers spending more time per pull request cleaning up after it.
A 15-minute session with no warning is a wall for anyone who needs longer to fill in a form. What WCAG 2.2.1 asks for, why the auth_cookie_expiration filter on its own is not enough, and how I handle warnings and auto-save.
Most visual UI state does not need JavaScript. This is the radio state machine: radio inputs plus :has() and :checked driving toggles, panels and swatches in WordPress and WooCommerce, without breaking keyboard or screen reader access.
Big-bang redesigns of legacy systems usually end in a blown budget and a broken database. What works instead: mapping dependencies, measuring the slow paths, and choosing a migration strategy that keeps production up.
How I stopped managing calendar range styling in JavaScript. The :nth-child(of) syntax plus the sibling combinator handles the highlight in CSS, leaving JS to do nothing but keep two checkboxes in sync.
Cascade layers, the :is() pseudo-class and selector doubling all settle specificity conflicts without !important. Plus the few cases, like utility classes and accessibility overrides, where !important is still the right call.
