Richard, bundle of thanks for you together with THEME TEAM taking extra steps in assisting towards the visuals. I will surely try that, but as of now I had removed fw from my sites for consistence look across all major themes, as my Moodles are my own to play with, so I keep on testing different visual possibilities in terms of HCI and likely FW elements in an HTML block MAY not be interactive at all for end users.
Thanks again for the code
