An external style sheet is also called a(n) _________ style sheet.

An external style sheet is commonly referred to as a linked style sheet. This terminology is derived from the way external style sheets are incorporated into HTML documents. When you use an external style sheet, you create a separate .css file that contains all your CSS rules. This file is then linked to your HTML document using a specific link element in the head section of the HTML. This linkage allows the HTML to apply the styles defined in the external file, thus maintaining a clear separation between content and design.

The primary advantage of linked style sheets is that they can be reused across multiple HTML documents, promoting consistency and ease of maintenance in web design. This method makes it easy to manage styles, as any changes made to the external CSS file automatically reflect across all the linked HTML files.

In contrast, inline and internal style sheets refer to styles defined directly within individual HTML elements or within a specific document, respectively, which does not provide the same level of reusability and organization as a linked style sheet. The term static generally refers to non-responsive design principles and does not apply to the concept of styling sheets directly.
