title: How to apply custom styles by tag
|
|
type: text/vnd.tiddlywiki

You can apply custom styles to tiddlers that have a particular tag by defining a CSS class with the name `tc-tagged-<Tag Name>`.
|
|
|
|
For example, to make tiddlers tagged "NightReader" appear in a special colour scheme suitable for night-time reading, [[create a stylesheet|Using Stylesheets]] defining the class `tc-tagged-NightReader` like this:
|
|
|
|
```
|
|
.tc-tagged-NightReader {
|
|
background-color:black;
|
|
color: orange;
|
|
padding: 35px 35px;
|
|
}
|
|
|
|
.tc-tagged-NightReader .tc-tiddler-body {
|
|
font-size: 1.5em;
|
|
}
|
|
```
|
|
|
|
The `tc-tagged-NightReader` class is applied to the entire tiddler and not just the tiddler text. If you want to target a smaller portion of the tiddler you can qualify the CSS selector, as is done here with `.tc-tagged-NightReader .tc-tiddler-body`.
|
|
|
|
Note that tags containing spaces or non-alphanumeric characters will be converted using URI encoding, making the generated CSS classname hard to predict. For example:
|
|
|
|
|!Tag |!Generated Class Name |
|
|
|`$:/mytag |`tc-tagged-%24%3A%2Fmytag` |
|
|
|`one two` |`tc-tagged-one%20two` |
|
|
|`£35.23` |`tc-tagged-%C2%A335.23` |
