Generally you put code and html stuff in the "peck marks" quotes to have it show up properly on the forum. On the PC US keyboard this is the character under the tilda. Unfortunately, that is the one character I do not know how to show on the forum.
e.g.
`
<ul class="CCC">
[*]xxxx
[*]yyyy
</ul>
`
I can reproduce this problem. We will look into it.
