Explain how hyperlink is added to a webpage?

In computing, a hyperlink is a reference to data that the reader can directly follow either by clicking or by hovering or that is followed automatically.

A hyperlink has an anchor, which is the location within a certain type of a document from which the hyperlink can be followed only from the homepage; the document containing a hyperlink is known as its source code document.

In some hypertext, hyperlinks can be bidirectional: they can be followed in two directions, so both ends act as anchors and as targets. More complex arrangements exist, such as many-to-many links.
