About
AdChoices is a self-regulatory standard for online interest-based advertising that gives consumers enhanced control over the collection and use of their data to deliver relevant ads.
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.
