Sharing examples of simulating sine and cosine curves in css animation
Let’s write a css3 parabola animation today = =
Parabola animation from left to right, let’s temporarily divide the action into uniform rightward movement and variable speed up and down movement.
For horizontal uniform motion, we can use translateX(x): define 2D transformation and move elements along the X axis; and linear: the speed of the animation is the same from beginning to end. These two attribute values To achieve;
up and down uniform speed motion can use translateY(y): define 2D transformation, move the element along the Y axis; and ease-in-out: the animation starts at a low speed and Finish.
1.html
<div id="container">
<div class="demobox">
<div class="demo"></div>
</div>
<div class="demobox">
<div class="demo"></div>
</div>
</div>Make the p of the demobox move to the right at a constant speed, and the p of the demobox inside will move up and down with variable speed.
2.css
#container {
height:110px;
font-size:0;
width:140px;
}
.demobox {
float:right;
width:5px;
height:5px;
animation:myfirst1 linear 5s infinite;
-webkit-animation:myfirst1 linear 5s infinite;
}
.demo {
width:6px;
height:6px;
border-radius:3px;
background:#90e4e9;
animation:myfirst2 ease-in-out 1s infinite alternate;
-webkit-animation:myfirst2 ease-in-out 1s infinite alternate; /*Safari and Chrome */
}
.demobox:nth-of-type(1) .demo:nth-of-type(1){
animation-delay:0s;
}
.demobox:nth-of-type(2) .demo:nth-of-type(1){
animation-delay:0.03s;
}
@keyframes myfirst1
{
from {
transform:translateX(0px);
-webkit-transform:translateX(0px);
}
to {
transform:translateX(1000px);
-webkit-transform:translateX(1000px);
}
}
@-webkit-keyframes myfirst1 /* Safari and Chrome */
{
from {
transform:translateX(0px);
-webkit-transform:translateX(0px);
}
to {
transform:translateX(1000px);
-webkit-transform:translateX(1000px);
}
}
@keyframes myfirst2
{
0% {
transform:translateY(0px);
-webkit-transform:translateY(0px);
}
50% {
transform:translateY(100px);
-webkit-transform:translateY(100px);
}
100% {
transform:translateY(0px);
-webkit-transform:translateY(0px);
}
}
@-webkit-keyframes myfirst2 /* Safari and Chrome */
{
0% {
transform:translateY(0px);
-webkit-transform:translateY(0px);
}
50% {
transform:translateY(100px);
-webkit-transform:translateY(100px);
}
100% {
transform:translateY(0px);
-webkit-transform:translateY(0px);
}
}ok, a sine and cosine curve comes out @^-^@
