height: 200px;
background-color: #000000;
margin-bottom: 20px;
}
// The mouse changes the width
.trasition-1{

// transition: width 2s linear 1s;
transition: width 2s linear;
&:hover{

width: 500px;
}
}
// The mouse rotates
.trasition-2{

transition: transform 2s ease-out;
&:hover{

transform: rotate(45deg);
}
}

animation Animation

grammar

animation: name duration timing-function delay iteration-count direction fill-mode play-state;

The name of the animation (name)@keyframes

Transition time (duration)

Time function (timing-function)

Delay time (delay)

plays (iteration-count)

Play direction (direction) Take turns playing and playing backwards

Stop playing state (fill-mode)

Whether to suspend (play-state)

.box{

width: 200px;
height: 200px;
background-color: #000000;
margin-bottom: 20px;
}
// The mouse moves through
.animation-1{

&:hover{

animation: move 2s linear;
}
}
@keyframes move{

100%{

transform: translateX(200px);
}
}
// The ball rolls
.animation-2{

border-radius: 50%;
animation: jump 2s cubic-bezier(0.4,-0.04, 0.94, 0.29) infinite;
}
@keyframes jump{

0%{

transform: translateX(0px);
}
40%{

transform: translateX(200px);
}
60%{

transform: translateX(200px);
clip-path: ellipse(50% 50% at 50% 50%);
}
100%{

transform: translateX(0px);
clip-path: ellipse(50% 45% at 50% 48%);
}
}
// Chrysanthemum rotation
.animation-3{

width: 100px;
height: 111px;

100%{

transform: rotate(360deg);
}
}

Time function

Time function : Manage the speed curve for animation playback in unit frames
The mathematical function of cubic Bessel function
Default :

  • linear uniform
  • ease
  • ease-in
  • ease-out
  • ease-in-out

steps It works for every keyframe , Not the whole time

Transition and animation in js Monitoring in

animationstart
animationend
