Description: The
tag is a fundamental part of an HTML document that contains metadata about the document. This section is not displayed directly in the browser, but it is crucial for the functioning and optimization of the web page. Within the tag, elements such as the document title, links to CSS stylesheets, JavaScript scripts, and metadata describing the content of the page can be included. Proper use of this tag allows search engines to index the content correctly and browsers to interpret the page’s presentation accurately. Additionally, the tag contributes to accessibility and usability by providing information that can be used by assistive technologies. In summary, although it is not visible to the end user, the tag plays a crucial role in the structure and functionality of a website.History: The
tag was introduced with the first version of HTML in 1993, as part of an effort to better structure information on web pages. As HTML evolved, new features and elements were added to the tag, such as metadata and links to stylesheets. With the arrival of HTML5 in 2014, many of these features were consolidated, allowing for greater flexibility and control over the presentation and behavior of web pages.Uses: The
tag is primarily used to define metadata that is not visible on the page but is essential for its functioning. This includes defining the page title, which appears in the browser tab, as well as including links to CSS stylesheets and JavaScript scripts. Metadata is also used to enhance SEO, such as tags that describe the content of the page and relevant keywords.Examples: A practical example of the
tag is as follows:
