Differences Between HTML 4.01 and HTML5
In HTML 4.01, the <a> tag could be either a hyperlink or an anchor. In HTML5, the <a> tag is always a hyperlink, but if it has no href attribute, it is only a placeholder for a hyperlink.
HTML5 has some new attributes, and some HTML 4.01 attributes are no longer supported.
