About

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.

OAuth is an open standard authorization protocol that allows applications to obtain limited access to user accounts without sharing passwords across web, mobile, and desktop environments.

It uses token-based authorization with access and refresh tokens, lets users grant specific permissions to applications such as access to profile data or contacts, and is widely adopted by online service providers such as Google, Facebook, Microsoft, and GitHub.
