! 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}`,<br>e.g. `tc-tagged-introduction`<br><br>''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>
```

Docs fix: Remove erroneous "class" attribute from tiddler widget The tiddler widget doesn’t generate any DOM nodes, and so wouldn’t have anything useful to do with a “class” attribute in any case. 2017-09-01 10:13:39 +00:00			`modified: 20170901101236822`

Split "transclude" widget into a separate "tiddler" and "transclude" widget Belatedly realised that the design would be clearer without these two separate concepts being conflated into a single widget. As a result of this change, any other widget or template that generates transclude widgets has needed adjustment. 2013-08-24 15:45:45 +00:00			`title: TiddlerWidget`
