Change Button colors on hover

This will need to be done in CSS at a theme level.
The class names given to the active and default state should have hover and active rules.

Hi stoboe – this works for me, and should give you a head start –

.caldera-grid .btn-default {
  font-family:
  border-color:
  color:
  min-width:
  background-color:}

.caldera-grid .btn-success {
min-width:
font-weight:}

.caldera-grid .btn-default:hover {
background-color:
border-color:
color:}
