Tooltips - Mediawiki
From Help Wiki
Create tooltips by utilizing the installed extension SimpleTooltips. See https://www.mediawiki.org/wiki/Extension:SimpleTooltip for syntax help.
Usage
There is a short alias and a more descriptive parser function name for each tooltip type.
Inline-text tooltip
{{#tip-text: text | tooltip-text}}
{{#simple-tooltip: text | tooltip-text}}
Info-icon tooltip:
{{#tip-info: tooltip-text }}
{{#simple-tooltip-info: tooltip-text }}
Inline-Image tooltip:
{{#tip-img: /path/to/your/image.png | image tooltip-text }}
{{#simple-tooltip-img: /path/to/your/image.png | image tooltip-text }}
Note: The "tip-img" and the "simple-tooltip-img" parser function respectively do not resize the image set to be shown, i.e. the image must be uploaded in an appropriate size like e.g. 16px x 16px.
