What is the function of base tag

The main function of the

base tag is to specify the default address or default target for all links on the page.

The base tag is the base URL tag in the HTML language. It is a single tag located within the head tag of the web page header file. A page can use at most one base element, which is used to provide a specified default target and can also be regarded as a markup that expresses paths and connection URLs. The main function of the

base tag is to specify the default address or default target for all links on the page. Among the common URL path forms, there are two types: relative paths and absolute paths. If the base tag specifies a target, the browser will use this target to resolve all relative paths in the current document, including URLs in tags such as a, img, link, and form. In other words, when the browser parses these tags, it will automatically add the target specified by the base tag before the path, thereby converting the relative path in the page into an absolute path.

Therefore, the main function of the base tag is to change the way the browser parses relative URLs so that it no longer relies on the URL of the current document, but uses the URL specified in the base tag to parse all relative URLs. This facilitates more flexible and convenient management of links and paths in web design and development.
