Ordered List
<OL> tag is used to create Ordered List in a HTML page. For example: <HTML><BODY> <OL type="I"> <LI>Apple</LI> <LI>Banana</LI> </OL>...
OL stands for an Ordered List whereas UL Stands for an un-ordered list Let us say you have a code like below <ol> <li>AAA</li> <li>BBB</li> <li>CCC</li>...
Tags that do not have a closing tag will probably not render. If it's somthing like the <html> tag or the <body> tag, the whole web page may not work.
</body>
