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.
YAML ("YAML Ain't Markup Language") is a human-readable data serialization language designed for representing structured data and exchanging it between systems and programming languages.
It uses indentation-based syntax with minimal structural characters, represents data using three core primitives such as mappings, sequences, and scalars, and includes features such as anchors and aliases for referencing data, along with a simple typing system for numbers, strings, and booleans.
