Q: I want to implement a styleswitcher only on a seperate “preferences”-page – how can I activate it nevertheless on other pages?
A: Inserting only the header-logic (and not the actual style-list) is currently not supported by default, but you can workaround this issue: Just hide the style-list via CSS (ul#yourId {display: none;}) and un-hide it on the “preferences”-page with a more specific CSS, e.g. By setting an id to the bodyTag by
page.bodyTag = <body id=”preferences”>
and overwrite the CSS-setting (#preferences ul#yourId {display: block;}. It's a little hacky, but hey – it works :)
