What is a CSS code or graphic that users can click on to link to another source called?

The term that refers to a CSS code or graphic that users can click on to link to another source is commonly known as an anchor. In HTML, the anchor element is designated by the <a> tag, which allows the creation of hyperlinks. This element can be styled with CSS to appear as a button or any graphic a developer designs. When a user clicks on an anchor, they are typically redirected to another web page, a different section of the same page, or any resource as specified in the href attribute.

While buttons can also serve as means for navigation in web interfaces, they usually involve form submission or actions initiated by JavaScript. An image map allows certain areas of an image to link to different URLs but is a more specific feature and not the general term for clickable links. Hence, defining it as an anchor highlights its specific role in linking and navigation within web development.
