How To Animate Old Bouncy Disney Style
The smooth bounciness animation can be done with the assist of HTML and CSS. Information technology will generate fun and desired outputs.
For this project, a unproblematic div with class brawl is needed in HTML page:
Nosotros will switch to CSS for animation programming. Now, Flexbox is used to accept the brawl at the middle of the folio and make the ball 70px past 70px in size. Information technology can be taken in any size of the user's option as information technology determines the size of the ball.
body {
display : flex;
justify- content : center ;
}
.ball {
width : 100px ;
tiptop : 100px ;
border-radius: 50% ;
background-color : #FF5722 ;
}
Hither,
justify-content: centre is used to centre the brawl horizontally.
border-radius : l% turns the square into a circle.
background-colour: #FF5722 turns the circle to orange colour. In that location are various code notations for colors to be remembered.
Keyframe creating: Keyframes in CSS animations gives consummate control over the blitheness. Simple use of the keyword @keyframes followed by the proper name of the animation, i.east, smooth bounce ball:
@keyframes smoothbounceball{
statements
}
Within the keyframe, employ keywords from and to to brand a starting time and end bespeak for the blitheness.
@keyframes smoothbounceball{
from { }
to { }
}
To our understanding, nosotros can add together starting and catastrophe values to the blitheness. To create a bouncing effect, we need to transform the location of the ball. transform allows to modify co-ordinates of a given element. Hence the last keyframe:
@keyframes smoothbounceball{
from { transform: translate 3 d( 0 , 0 , 0 );}
to { transform: translate three d( 0 , 200px , 0 );}
}
Here, translate3d functions takes iii inputs, the change in 3-dimensional axis (x, y, z). It will translate the ball in 3-Dimensional axes. If the ball wants to motility up and down, the ball needs to translate forth the y-axis.
Running the keyframe: Since the @keyframe has been created, now it needs to run. In the higher up mentioned code of .ball{ }, a following a line has to be added:
.ball{
Given statements...
blitheness: bounciness 0.5 s;
animation- management : alternate;
animation-iteration-count: infinite;
}
The agreement of the animation: The blitheness tells brawl chemical element to use the given keyframe rule bounciness and sets the length of the animation of 0.5 seconds. So at finishing, the animation management alternates. And so runs the animation an space number of times.
Merely it does non similar the ball bounces just moves back and along, up and down.
Hence, it looks like:
That is considering the timing of the blitheness is off. Animations are set to ease, by default. So, to look like the ball is bouncing, the animation needs to be wearisome at the start and speeding up in the center and then finishing slowly.
Hence bezier curve is used to customize animation timings. Therefore the code:
.ball{
Given statements..
animation: bounce 0.5 south cubic-bezier( 0.v , 0.05 , 1 , 0.5 );
}
Later this, the ball shows the billowy consequence. Here is the final code:
<!DOCTYPE html>
< html >
< caput >
< style >
body {
display: flex;
justify-content: heart;
}
.ball {
width: 100px;
tiptop: 100px;
border-radius: 50%;
background-color: #FF5722;
animation: bounce 0.5s;
animation-direction: alternate;
blitheness-timing-office: cubic-bezier(.5, 0.05, 1, .5);
animation-iteration-count: infinite;
}
@keyframes bounce {
from {
transform: translate3d(0, 0, 0);
}
to {
transform: translate3d(0, 200px, 0);
}
}
/* Prefix Back up */
ball {
-webkit-animation-proper name: bounciness;
-webkit-animation-duration: 0.5s;
-webkit-animation-direction: alternate;
-webkit-blitheness-timing-function: cubic-bezier(
.5, 0.05, i, .v);
-webkit-animation-iteration-count: infinite;
}
@-webkit-keyframes bounce {
from {
-webkit-transform: translate3d(0, 0, 0);
transform: translate3d(0, 0, 0);
}
to {
-webkit-transform: translate3d(0, 200px, 0);
transform: translate3d(0, 200px, 0);
}
}
