Like teacher or other where to say, you need to follow the html rules, you need to follow what they told you that use the correctly tags name. If not, the printout will not show correctly. But when I randomly change the tags name to <alien> or <anytagisok> the web still show ok, same as use <p> tags, please tell me the reason. If it's in the explore has default think if a character has a "<>" if we couldn't understand it, we will treat it like <p>.
Or if we use any other tags when we use in the css or javascript it will not work well. Please tell me the reason, Hope somebody help me. Thank you.
