! 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">
