First type this

<OL TYPE="I">

Then before each of the items in your list just type this

<LI>

When you've finished your list close it off by typing this

</OL>

So a list like this-

1. First item
2. Second item
3. Third item
4. Fourth item

Would have HTML that looks like this

<OL TYPE="I">
<LI>First item
<LI>Second item
<LI>Third item
<LI>Fourth item
</OL>

You can make the words in your list coloured by simply typing the tag instructions for changing the font colours.

So a list that looks like this-

1. First item
2. Second item
3. Third item
4. Fourth item

Would have HTML that looks like this

<FONT COLOR="BLUE">
<OL TYPE="I">
<LI>First item
<LI>Second item
<LI>Third item
<LI>Fourth item
</OL>
</FONT>

If you'd prefer lower case Roman Numerals, then just change your TYPE="I" to TYPE="i" like this

<FONT COLOR="BLUE">
<OL TYPE="i">
<LI>First item
<LI>Second item
<LI>Third item
<LI>Fourth item
</OL>
</FONT>

And it will look like this-

1. First item
2. Second item
3. Third item
4. Fourth item
