Web & Frontend Listed
standards
Senior front-end engineering standards for CSS architecture, TypeScript patterns, design-system conventions, forms, client-side security, async/state handling, testing, accessibility (WCAG 2.2 AA), and performance (Core Web Vitals). Framework-agnostic — applies to React, Vue, Svelte, Angular, Astro, or vanilla HTML/CSS/JS, and to plain styling/markup work with no framework at all. Use whenever writing, reviewing, refactoring, or debugging UI code, component APIs, CSS, forms, or client-side data handling — including symptom-shaped questions ("why is this element jumping", "why doesn't z-index work", "this modal detaches on scroll") that never name a framework or a standard.
