Headless UI

A microinteraction is a small, contained moment in a user interface that accomplishes a single task — a button animation on click, a toggle switch, a pull-to-refresh gesture, or a "like" heart animation. These subtle design details provide feedback, guide users, and add personality to an interface. Well-crafted microinteractions make products feel polished and responsive without overwhelming users.

Figma is a browser-based collaborative design tool used for creating UI designs, prototypes, and design systems. Its real-time multiplayer editing, component system, auto layout, and dev mode have made it the industry standard for product design. Developers use Figma to inspect designs, extract CSS values, export assets, and — through plugins and APIs — automate the design-to-code workflow.

Dark mode is a UI color scheme that uses light-colored text and elements on a dark background. It reduces eye strain in low-light environments, can save battery on OLED screens, and has become an expected feature in modern applications. Implementation typically involves CSS custom properties or design tokens that switch between light and dark theme values, often respecting the user's system-level preference via the `prefers-color-scheme` media query.

Breadcrumb navigation is a secondary navigation pattern that shows the user's current location within a site hierarchy as a trail of links (e.g., Home > Products > Shoes). It helps users understand where they are and quickly navigate back to parent pages without relying on the browser's back button. Proper implementation uses an ordered list within a `<nav>` element with `aria-label="Breadcrumb"` for accessibility.

Deep linking is the ability to direct users to a specific screen or content within a mobile or web application via a URL, rather than just opening the app's home screen. In React Native and Flutter, this involves configuring URL schemes (e.g., `myapp://profile/123`) or universal/app links that work across platforms. Deep linking is essential for push notification routing, marketing campaigns, sharing content between users, and creating seamless web-to-app transitions.

Dart is the programming language created by Google and used as the sole language for Flutter development. It features a sound type system, null safety, async/await support, and compiles both ahead-of-time (AOT) for production performance and just-in-time (JIT) for fast development cycles with hot reload. Dart's syntax feels familiar to developers coming from JavaScript, TypeScript, Java, or Kotlin, making the transition to Flutter relatively smooth.
