What is HTML - Hypertext Markup Language Basics
HTML, known as Hypertext Markup Language, is a platform-independent style collection used for designing web pages. It allows for the creation of textual documents with links, specified through markup tags. Markup language uses special tags to format text and adjust elements like fonts, lists, forms, images, and tables. HTML documents utilize tags enclosed in brackets and are case-insensitive. Employing white space in HTML documents enhances readability. Some tags have attributes for additional characteristics, and comments are included within specific markers. HTML plays a crucial role in web development and content presentation.
