Hi Yigit

Thanks for your response. I made the following modifications to the code snippet you supplied. This seems to look correct and it behaves responsively now. Cheers.

#your-unique-id {
  max-width: 984px;
  margin: 20px auto;
}

Thanks very much Yigit, this works to remove the captions on the 3 boxes. Perhaps I was unclear but I also would like to have those 3 boxes in colour at all times – not just on hover. What would be the additional code to achieve this?
Cheers
