🆚 CSS vs. IDN

Cascading Style Sheets (CSS) is a stylesheet language used to control the presentation of HTML and XML documents, defining layout, colors, typography, and responsive behavior across different devices.

It uses a cascading and specificity model to resolve style conflicts, supports reusable rules and selectors, and includes layout systems such as Flexbox and Grid, media queries for responsive design, and features for animations, transformations, and advanced text formatting.

Modern CSS features enable complex responsive interfaces and dynamic styling without JavaScript, including container queries, the :has() pseudo-class, the light-dark() function, native nesting, subgrid layouts, custom properties, and view transitions.

Internationalized Domain Names (IDNs) allow people around the world to use domain names in local languages, such as Arabic, Chinese, or Cyrillic.
