The Source button stack allows to customise the border, background and text colour. In addition, the background colour in the ‘hover’ state can also be defined. What is missing, however, are the border and text colour in the ‘hover’ state. This would allow e.g. a nice color inversion upon hovering.
While the stack doesn’t offer these settings directly, is there possibly some CSS trickery to define those colours for the ‘hover’ state ?
Thanks everyone for sharing your expertise.
