You can use data attributes for animation names, delays, and durations if you want to get support from Javascript. Or you can use helper classes like .animation-delay-600 or .animation-duration-400. You must use Goldman for these helper classes.

You will see :root in the downloaded files to customize --rotateIn animation.

@keyframes rotateIn {
    from {
        opacity: 0;
        transform: var(--rotateIn);
    }
    to {
        opacity: 1;
        transform: resetTransform();
    }
}

You can set the all values for rotateIn animation; animation duration and animation delay.

<div class="some-goldman-classes animated" data-animation="rotateIn"
     data-animation-delay="250" data-animation-duration="600">
     Some great content…
</div>

You can actively use these animations as a group. Just what you need; Give the container the class .group and give the element you want to animate with the animation you want, starting with .group-hover-.

You can use them directly in your portfolio works. You can have great animations without writing any css. It will work great on mobile devices.

These animations can be given to as many items as you want. You can give them different delay, duration and animation.
