The upcoming Tiki 26 will feature color modes, made possible by Bootstrap 5.3. Users will be able to switch between light and dark modes, initially. The switch can also be automatic, based on the user's browser setting.
By the time Tiki 26 is released, there will be a Switch Color Mode module that can be assigned to enable switching. In the meantime (before the module is available), for anyone who has a Tiki master or branch 26 installation and wants to check out color modes, the code below can be used. This code uses HTML and JavaScript from the color mode demo pages at getbootstrap.com.
Make a page named, for example, "Color_mode_switch" with the following code as its content. After saving the page edit, the switch will work immediately on most themes in the Tiki package (a few dark themes don't have alternative color versions). Then make a new "Menu page" module and assign it to a module zone where it will be available on all pages.
