Hi,
Sorry to confuse .. the screen grab you have is the Home page (the text position when I hover is fine) .. I am referring to the linked pages where you can see a gallery block of thumbnail images (linked to Vimeo videos).
I have been able to centre the titles over the thumbnails when I hover (yay!) however discovered another "glitch" ... when you hover near the text, the opacity becomes 0 and the hover "hand" changes to a curser and therefore you cannot activate play the linked video?
I've taken two screenshots to explain (on my "Tabletop/Food" page - the 1st shows where I hover near the text, and the curser changes to an "arrow" and 0 opacity .. the 2nd shows the setting I want all over the thumbnail when I hover, the curser as a hand and .75 opacity, as well as being able to play the video..
