The <!DOCTYPE html> declaration specifies the HTML version and helps browsers render web pages correctly by indicating the document type and version. It ensures consistent and standardized interpretation of HTML code across different browsers.
An HTML element is a fundamental building block of a web page, consisting of an opening tag, content, and a closing tag. It defines the structure and content of the page, with tags written in angle brackets (< >). Elements can include attributes for additional information.
The <head> element in HTML is used to contain meta-information about the document, such as the title, character set, styles, scripts, and other metadata. It provides essential details for the browser and search engines but does not contribute directly to the visible content of the web page.
The <body> element in HTML contains the main content of a web page, including text, images, links, and other elements that users see and interact with when viewing the page in a browser. It represents the visible part of the webpage.
