Head Code
A head code in web development refers to the section of HTML that is placed within the tags of a webpage's structure. This section is not visible to users but is crucial for defining the page's metadata, linking to external files like CSS stylesheets and JavaScript files, setting the character set, defining the viewport for responsive design, and including other meta tags like title and description. The head code is essential for search engine optimization (SEO), ensuring proper page rendering and behavior, and integrating with external services and functionalities.
