If you followed the tutorial, you created
1. a php file
2. a template in AdminCP.
Where do you add your html code, to 1 or 2? You need to add it to 2. It may be that you need to put a div-container around your html, since the formatting of unordered lists and the like will be reset by vB in order to format the page layout.
Do
HTML Code:
<div class="mytext">
<ul>
<li>blah blah</li>
</ul>
</div>
Add, for example, this to additional.css:
HTML Code:
.mytext ul {
whatever css formatting you want
}
But this really leads away from this tutorial.
