שינוי חנות

אוקי מצוין כיוון אולי גם יעזור

אהה מצאתי את ההגדרות

.image-link .overlay-image::before, .image-link .overlay-image::after {
border-color: #fff;
}
.image-link .overlay-image::before {
border-bottom: 1px solid;
border-top: 1px solid;
transform: scale(0, 1);
}
.image-link .overlay-image::after, .image-link .overlay-image::before {
bottom: 20px;
content: "";
left: 20px;
opacity: 0;
position: absolute;
right: 20px;
top: 20px;
transition: opacity 0.5s ease-in-out 0s, transform 0.55s ease 0s;
}
*::before, *::after {
box-sizing: border-box;
}
.image-link .overlay-image::before, .image-link .overlay-image::after {
border-color: #fff;
}
.image-link .overlay-image::after {
border-left: 1px solid;
border-right: 1px solid;
transform: scale(1, 0);
}
.image-link .overlay-image::after, .image-link .overlay-image::before {
bottom: 20px;
content: "";
left: 20px;
opacity: 0;
position: absolute;
right: 20px;
top: 20px;
transition: opacity 0.5s ease-in-out 0s, transform 0.55s ease 0s;
}
*::before, *::after {
box-sizing: border-box;
}
.image-link .overlay-image {
background: rgba(0, 0, 0, 0.5) none repeat scroll 0 0;
}
.image-link .overlay-image {
height: 100%;
left: 0;
opacity: 0;
padding: 19px;
position: absolute;
top: 0;
transition: opacity 0.5s ease-in-out 0s, transform 0.5s ease 0s;
width: 100%;
z-index: 2;
}
* {
box-sizing: border-box;
}
*::-moz-selection {
background: #000 none repeat scroll 0 0;
color: #fff;
}

צריך להכניס את זה בקובץ function?
