Thank you. I thought I wasn’t able but now I think I got the code by myself and, even better, it works only for the carousel widget and it doesn’t have effect on the rest of widgets. I share it here just in case it’s useful for someone in the future. It’s simple and this should be added in style.php:
/* COLOR SCREEN VISIBLE FROM THE BEGINNING */
.carousel-item figure.animated-overlay figcaption {
-webkit-transition: all 0.4s;
-moz-transition: all 0.4s;
-o-transition: all 0.4s;
transition: all 0.4s;
opacity: 1;
-moz-opacity: 1;
filter:alpha(opacity=100);
width: 100%;
height: 100%;
position: absolute;
top: 0;
left: 0;
z-index: 3;
-webkit-backface-visibility: hidden;
-webkit-perspective: 1000;
text-align: center;
}
/* TITLE VISIBLE FROM THE BEGINNING */
.carousel-item figure.animated-overlay figcaption .thumb-info h4, figure.animated-overlay figcaption .thumb-info h5, figure.animated-overlay figcaption .thumb-info-alt i {
-o-transform: translateY(0%);
-moz-transform: translateY(0%);
-webkit-transform: translateY(0%);
transform: translateY(0%);
opacity: 1;
-webkit-transition: all 0.4s;
-moz-transition: all 0.4s;
-o-transition: all 0.4s;
transition: all 0.4s;
}
/* TITLE VANISHES */
.carousel-item figure.animated-overlay:hover figcaption .thumb-info h4 {
-o-transform: translateY(100%);
-moz-transform: translateY(100%);
-webkit-transform: translateY(100%);
transform: translateY(100%);
opacity: 0;
}
/* COLOR SCREEN VANISHES */
.carousel-item figure.animated-overlay:hover figcaption {
opacity: 0;
-moz-opacity: 0;
filter:alpha(opacity=0);
}
