About

Hypertext Markup Language (HTML) is a markup language used to create web pages and is the de facto standard for documents displayed in web browsers.

It defines the structure of web content using elements for text, links, images, forms, tables, and embedded media, organizes documents into a hierarchical DOM, and enables hyperlinking between pages, which is a fundamental mechanism of the World Wide Web.

OpenAPI is a specification language for defining HTTP APIs, typically written in YAML or JSON.

It enables automated generation of interactive documentation (via tools such as Swagger UI and Redoc), schema-based request and response validation, automatic creation of client SDKs and server stubs in multiple programming languages, and integration into CI/CD pipelines.
