What is a tag to use roman number in an ordered list?

Answer 1

As we know <OL> tag is used for making Ordered Lists. <OL> tag has two attributes - TYPE and START.
TYPE attribute is used to assign a particular type of character to it and this the only one which will help in this case.
Now, the TYPE attribute specifies following numbering patterns -
a) <OL TYPE="1">
b) <OL TYPE="I">
c) <OL TYPE="i">
d) <OL TYPE="A">
e) <OL TYPE="a">
Now, you are smart enough (or I guess more than that) to decide that b) <OL TYPE="I"> and c) <OL TYPE="i"> will help you make Ordered List with Roman Numbers.
Ex (1) for capital Roman letters,
<OL TYPE="I">
<LI> Art</LI>
<LI>Craft</LI>
<LI>Music</LI>
<LI>Games</LI>
</OL>
Ex (2) for small Roman letters,
<OL TYPE="i">
<LI> Art</LI>
<LI>Craft</LI>
<LI>Music</LI>
<LI>Games</LI>
</OL>
