More Advanced Keyframe Animations
A fadeIn keyframe animation has been started. Style the element to be completely hidden in its starting state. Hide it in a way that will allow us to fade it in.
@keyframes fadeIn {
0% {
opacity:;
visibility: hidden;
}
100% {
}
}
Complete the animation by making the end state visible.
@keyframes fadeIn {
0% {
opacity:;
visibility: hidden;
}
100% {
opacity:;
visibility: visible;
}
}
Apply the fadeIn animation to the .modal-overlay when it is .active.
@keyframes fadeIn {
0% {
opacity:;
visibility: hidden;
}
100% {
opacity:;
visibility: visible;
}
}
.modal-overlay.active{
animation: fadeIn .25s;
}
Finally, in order to make the overlay stay visible after it is done animating, give the animation a fill-mode of forwards.
@keyframes fadeIn {
0% {
opacity:;
visibility: hidden;
}
100% {
opacity:;
visibility: visible;
}
}
.modal-overlay.active{
animation: fadeIn .25s forwards;
}
Create a slideUp keyframe animation.
Have the slideUp animation start by moving down (translating Y) by 400px.
End the animation by moving up (translating Y) by -300px up the page.
@keyframes slideUp{
from {
transform: translateY(400px);
}
to{
transform: translateY(-300px);
}
}
The fadeIn animation has already been applied for you to the modal when active. Now apply the newly created slideUp animation. Give the animation a0.65s duration with a 0.5s delay.
.modal.active {
animation: fadeIn 0.25s forwards, slideUp 0.65s 0.5s;
}
Give the slideUp animation a custom cubic bezier with these values 0.175, 0.885, 0.32, 1.275. This will cause the modal to slideUp, overshoot the -300px, and then slide back down to its resting spot at -300px. Neat, right?!
Finally, have the modal stay at its final resting state on the page, by giving theslideUp animation a fill-mode of forwards.
@keyframes slideUp{
from {
transform: translateY(400px);
}
to{
transform: translateY(-300px);
}
}
.modal.active {
animation: fadeIn 0.25s forwards, slideUp 0.65s 0.5s cubic-bezier(0.175,0.885,0.32,1.275) forwards;
}
