The <a> tag defines an anchor.
Supported In HTML4: Yes
Supported In HTML5: Yes
HTML4 vs HTML5 Differences: In HTML 4.01, the <a> tag could be either a hyperlink or an anchor. This was determined by the href attribute. In HTML 5, the <a> tag is always a hyperlink, but if it has no href attribute, it is only a placeholder for a hyperlink. HTML 5 has some new attributes, and some HTML 4.01 attributes are not supported in HTML 5.
