You may ask why not write it directly as Close

When making a web page, the parameters in the html language are used to specify the url of the link. #### is the link to this page. href="address" is the link to the address link. This page defaults to this page. No new window will pop up. When the connection is empty, If # is removed, the mouse hand cursor will not be displayed. In simple terms, it is a fake link pointing to this page
You can also follow # followed by the anchor id. This is actually another usage of a bookmark
