First we analyze the role of the html base tag:
The base tag is the base URL tag in the HTML language. It is a single tag located in the head tag of the web page header file. Within, a page can only use at most one base element, which is used to provide a specified default target, which can also be regarded as a mark that expresses the path and connection URL.
Common URL path forms include relative paths and absolute paths respectively. If the base tag specifies a target, the browser will use this target to parse all relative paths in the current document, including tags (a, img , link, form), that is to say, the browser will add the target given by base before the path when parsing, and the relative paths in the page will also be converted into absolute paths.
