I can get the window to pop-up when hovering over but I cannot get the style (look/color) to work.
I followed the poor instructions on the website with no luck.
You can override the default CSS of the tooltips by following three simple steps:
Add the line Logos.ReferenceTagging.lbsCssOverride = true;
somewhere between the line <script type="text/javascript">
and </script>
It would help to know what file it is to add the override. I assume the default template?
I also added the CSS code (provided) to the template.css
