Hypertext Markup Language (HTML) is fundamentally designed for defining the structure and content of digital documents intended for presentation within web browsers.
Answer: True
Explanation: HTML's primary role is to structure and define the content of web pages, enabling web browsers to interpret and render them accurately.
Web browsers interpret HTML code to render web pages, retrieving documents from local storage or remote web servers.
Answer: True
Explanation: Browsers parse HTML documents, whether sourced locally or from a server, to construct and display the visual representation of a web page.
The fundamental structural units of HTML documents are known as elements, which are constructed using tags enclosed in angle brackets.
Answer: False
Explanation: The core components are elements, formed by tags (e.g., <p>...</p>). Attributes provide additional information about elements, not the structural units themselves.
An HTML element typically comprises a start tag, an end tag, and the content situated between them; however, certain elements, such as <img>, are self-closing or empty elements.
Answer: True
Explanation: Most HTML elements consist of opening and closing tags enclosing content. Empty elements, like <img> or <br>, do not require closing tags.
Attributes within HTML tags serve to provide supplementary information or properties related to an element, rather than solely defining its content.
Answer: False
Explanation: Attributes provide metadata or modify the behavior/appearance of an element; they do not define the primary content itself, which is typically placed between tags.
