Never tried custom css before, my code isn't working but I don't know where I've gone wrong. The selector is right (it works for grayscale) but the hover effect of the thumbnail floating up a bit on hover isn't working.
any tips?
// image hover effect //
.portfolio-grid-overlay .grid-item .grid-image {
transition: 0.3s !important;
&:hover {
transition: 0.3s !important;
margin-top: -10px;
}
}
