How HTML tags work
HTML tags are used to organize and format the various elements and content of a web page. Each HTML tag usually consists of an opening tag and a closing tag, with the actual content in between. Tags are enclosed in angle brackets (<>) and may contain additional attributes to further affect the behavior or appearance of the tag.

: With the <a> tag (a stands for anchor), hyperlinks to other websites or files can be created. The 'href' attribute specifies the target URL, while 'target' and 'rel' can influence the behavior of the link.
