I don't know your situation, but these are the generic steps on tiddlywiki.com that will show you what to do there, you will have to modify them to your situation.
Make a tiddler with this in the text field: <div style='position: fixed; top: 10px; left: 200px; width: 300px; height: 100px; background-color: darkred; color: white; text-align: center; padding: 10px; border: none; border-radius: 2px; box-shadow: 10px 15px 30px grey; transition-duration: 0.4s; z-index:999; '> Bloop </div> give that tiddler the tag $:/tags/PageTemplate it should now be floating above everything else at the top of the screen, regardless of what other tiddlers are open or what story view you are using. Change the contents of that tiddler to change whatever you want to actually be displayed, add or remove the tag to make it visible or not. -- You received this message because you are subscribed to the Google Groups "TiddlyWiki" group.
