Thank you
To amend try adding the following to the Custom CSS field of your templates parameters (Extensions -> Templates -> [YourTemplateStyle] -> Custom CSS)....
(edit to taste)
.j51imagehover [class^="imghvr-"] figcaption {
background: rgb(255, 255, 255, .3);
}
.imghvr-blur:hover > img {
transform: none;
opacity: 1;
filter: none;
}
