This template detects whether it is being used with dark mode, and displays different content accordingly. This should however NOT be relied upon. For instance: It may not work with thedark mode gadget. You can use thebackground-image property with a URL insideTemplateStyles with different versions for dark mode and light mode instead.
Rationale
Some images and text need to be different depending on the mode selected by the user. This template provides an easy way to do that.
Usage
{{If dark|content for dark mode|content for light mode}}
By default,<span>...</span> tags are used to wrap the specified content. A different tag may be specified using|tag=
E.g.|tag=div can be used if the content contains block-level elements.
Notes
This template will only work with Wikipedia's official dark theme. It will not work with browser extensions such as Dark Reader orthe dark mode gadget, due to relying on the<html> tag having the.skin-theme-clientpref-night class.
This templatedoes not actually switch the content between the light and dark mode; it simply outputs both, and hides the content for the opposite theme using CSS.
Example
Normal usage
{{If dark|You are using dark mode!|You are using light mode!}} yields:
