I have got it sorted now thanks after spending a long time trolling through past support requests.
Hi rdellconsulting – thanks for taking the time to consider my issue.
My work in progress dummy site is here – http://www.rickharvey.nz/9ktb8b9e
The featured images are just yellow blocks – 270 x 250 – while I get things sorted.
It is the white area around the circles (either in non-hover or hover mode) that I wish to make the same colur as the background.
I hope that makes sense
Cheers, Rick
