This plugin uses the <a href="https://chrisbracco.com/a-simple-css-tooltip/" rel="nofollow ugc">Simple CSS tooltips</a> by Chris Bracco and a shortcode to create simple tooltips. You can define a link, tooltip location and more in the shortcode.
<ul>
<li><a href="https://profiles.wordpress.org/wouterpostmanl#content-plugins" rel="nofollow ugc">View my other plugins</a></li>
</ul>
To add a tooltip to your website, please install and activate the plugin. 
Then use the shortcode to add a tooltip:
<pre><code>[tooltip text="The tooltip"]The text[/tooltip]
</code></pre>
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:
<pre><code>[tooltip text="The tooltip" location="right" href="https://example.com/" rel="nofollow"]The text[/tooltip]
</code></pre>
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 “#”.

Easily add tooltips to your wordpress site. Tooltips will show when target element is hovered over. On mobile devices tooltips show when target element is tapped. You can easily pick your tooltip color settings in Settings > Simple Tooltips.
<h4>How to Use</h4>
To define a tooltip (new, easy way): Click the tooltip icon on your visual content editor to add the tooltip shortcode. Change the content attribute to whatever you want to be the content inside the tooltip bubble. Change the tooltip trigger to whatever content you want to be used to trigger the tooltip, when hovered. (see screenshots)
To define a tooltip (old way): Add class “tooltips” to the target html element. The title attribute will be used for tooltip content.
