To set the marker type, we can use the type attribute. For uppercase letters in alphabetical order, the value we need is A.

<html>
<body><ol type="A"><li>Harry</li><li>Hermione</li><li>Ron</li></ol></body>
</html>
]]>

See that? We've just used uppercase letters to organize our list alphabetically.

The attribute needs to go before the = sign and the value.
