Thanks! I was able to get it to work, but it is touchy to get the element to drop on top of the Link Block. I wish it was just possible to add the href to the image or icon directly (without going into code).
In the case of an Icon Block in a Link Block, the Icon size was greatly reduced and I can't find the right control to restore it to the original size. Do you know where that would be? Thanks.
