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.
SearchAction is a structured data type from Schema.org that describes a website's search capability.
Before November 2024, it was used by 
Google to enable the "Sitelinks Search Box" feature, which displayed a search bar for a website directly within the search results snippet. However, since Google deprecated this feature, there is no evidence that other search engines or apps currently support it.
