The <<.def tv-config-toolbar-class>> [[variable|Variables]] controls the value of the [[CSS|Cascading Style Sheets]] `class` attribute on the HTML element for a toolbar button.

It can be set prior to transcluding such a button.

In most environments, it defaults to <<.value tc-btn-invisible>>, which removes the button's background colour and border.
