HTML <head> Tag
Short Introduction to the <head> HTML Tag
The <head> tag is a key HTML tag that is used to outline the page’s metadata and resources. It is basically a container for data concerning the document, including the title, the character encoding, styles, scripts, and more. This <head> tag itself is not displayed to the user, but its role in processing, presenting, and interacting with the user through the browser and search engine remains crucial.
This guide is intended to sketch out the functionality of the <head> tag, its structural features, and the cardinal considerations in modern web development.
