dotted border-bottom height

This is a matter of styling. Copy the plugin’s stylesheet to your theme folder (should be plugins/tippy/dom_tooltip.css) and look in the first two sections: .tippy_link and .tippy_link:hover Find the line:

border-bottom: 1px dotted blue;

Replace that with whatever you wish. text-decoration will typically be closer to the text than a bottom border, but text-decoration is pretty inflexible; you can’t do much with it.

thanks Chris,

I’ve tried through the browser inspector first (not copied yet in the main css), but it worked only going down…

If I copy the rule in the main css do I have to delete it from the tipp-css? and do I have to refer to any of both css-files anywhere in the tippy files?

If you copy tippy.css from the plugin folder to your theme’s stylesheet, Tippy should automatically load it instead of its own copy.
