In simple terms, we can say it is a list of definitions (for example, glossaries to present the information on the internet/ web page). However, the usage of the Description list is less but have some purpose. Meanwhile, this definition lists gives added value to the web page; for example, the text given on the web page explains the context in other words in helping through semantically marking up the context. By doing this, we can easily extract the structured information. A definition list is a perfect term to describe the terms, values and another glossary.
Syntax:
<dl>
<dt>
……
</dt>
<dd>
………..
</dd>
</dl
