Introduction

The TiddlerWidget is used to set a value for the current tiddler variable, valid within the scope of the TiddlerWidget.

Content and Attributes

AttributeDescription

CSS Class Variables

The tiddler widget assigns several useful CSS classes to variables that it creates:

missingTiddlerClass
tc-tiddler-exists or...
tc-tiddler-missing depending on whether the tiddler exists
shadowTiddlerClass
tc-tiddler-shadow if the tiddler is a shadow tiddler
systemTiddlerClass
tc-tiddler-system if the tiddler is a system tiddler
tiddlerTagClasses
a space separated list of CSS classes named tc-tagged-{tagname},
e.g. tc-tagged-introduction

Note: tag names are URI encoded which means that the tag $:/tags/Macro appears as the CSS class tc-tagged-%24%3A%2Ftags%2FMacro. See How to apply custom styles by tag for more details

You can use these variables like this:

<$tiddler tiddler="MyOtherTiddler">
<div class=<<missingTiddlerClass>>>
<$transclude/>
</div>
</$tiddler>
