This plugin uses the Simple CSS tooltips by Chris Bracco and a shortcode to create simple tooltips. You can define a link, tooltip location and more in the shortcode.
To add a tooltip to your website, please install and activate the plugin. Then use the shortcode to add a tooltip:
[tooltip text="The tooltip"]The text[/tooltip]
The above shortcode will add a simple tooltip on top of «The text». If you want to include a link or change the location of the tooltip, this is possible by using the following attributes in your shortcode:
[tooltip text="The tooltip" location="right" href="https://example.com/" rel="nofollow"]The text[/tooltip]
The location can either be top, right, left or bottom. If you don’t enter a location, the default location (top) will be used. As you can see it is also possible to add rel=»nofollow» to your link. If you don’t enter a link, the text will link to «#».
