How can we do animations with only CSS

 
Download these examples

CSS allows animation of HTML elements without using JavaScript or Flash! Nice
All these properties @keyframes, animation-name, animation-duration, animation-delay, animation-iteration-count
animation-direction, animation-timing-function, animation-fill-mode, animation
Are supported in all these browsers:
 
How can we do animations with only CSS
 
When you specify CSS styles inside the @keyframes rule, the animation will gradually change from the
current style to the new style at certain times.
The following example binds the "example_1" animation to the div tag element.
The animation will last for 15 seconds, and it will gradually change the background-color of the div tag element
from "blue" to "yellow":
 

Example - 1 -

 
<html>
<head>
<style> 
 div{
  width: 500px;
  height: 50px;
  background-color: blue;
  animation-name: example_1;
  animation-iteration-count: infinite;
  animation-duration: 15s;
  font-weight:bold;
  font-size:36px;
  color:white;
}
@keyframes example_1 {
  from {background-color: blue;}
  to {background-color: yellow;}
  from {background-color: yellow;}
  to {background-color: blue;}
  
}
</style>
</head>
<body>
<div><center> DZOSOFT </center></div>
</body>
</html>
 

Example - 2 -

 
The animation-delay property specifies a delay for the start of an animation.
The following example has a 2 seconds delay before starting the animation
<!DOCTYPE html>
<html>
<head>
<style> 
 div{
  width: 50px;
  height: 50px;
  background-image:url('image/dzosoft.jpg'); 
  background-repeat: no-repeat;
  position: relative;
  animation-name: example_2;
  animation-iteration-count: infinite;
  animation-duration: 4s;
  animation-delay: 2s;
}

@keyframes example_2 {
  0%   {background-image:url('image/dzosoft.jpg'); left:0px; top:0px;}
  25%  {background-image:url('image/dzosoft.jpg'); left:400px; top:0px;}
  0%   {background-image:url('image/dzosoft.jpg'); left:400px; top:400px;}
  75%  {background-image:url('image/dzosoft.jpg'); left:0px; top:400px;}
  100% {background-image:url('image/dzosoft.jpg'); left:0px; top:0px;}
}
</style>
</head>
<body>
<div></div>
</body>
</html>
 

Example - 3 -

 
The animation-iteration-count property specifies the number of times an animation should run.
The following example will run the animation 5 times before it stops
<!DOCTYPE html>
<html>
<head>
<style> 
 div{
  width: 50px;
  height: 50px;
  background-image:url('image/dzosoft.jpg'); 
  background-repeat: no-repeat;
  position: relative;
  animation-name: example_3;
  animation-duration: 4s;
  animation-iteration-count: 5;
}

@keyframes example_3 {
  0%   {background-image:url('image/dzosoft_1.jpg'); left:0px; top:0px;}
  25%  {background-image:url('image/dzosoft_2.jpg'); left:200px; top:0px;}
  50%  {background-image:url('image/dzosoft_3.jpg'); left:200px; top:200px;}
  75%  {background-image:url('image/dzosoft_4.jpg'); left:0px; top:200px;}
  100% {background-image:url('image/dzosoft.jpg');   left:0px; top:0px;}
}
</style>
</head>
<body>
<div></div>
</body>
</html>
 

Example - 4 -

 
The animation-direction property specifies whether an animation should be played forwards,
backwards or in alternate cycles.
The following example will run the animation in reverse direction (backwards)
<!DOCTYPE html>
<html>
<head>
<style> 
 div{
  width: 50px;
  height: 50px;
  background-image:url('image/dzosoft.jpg'); 
  background-repeat: no-repeat;
  position: relative;
  animation-name: example_4;
  animation-duration: 4s;
  animation-direction: reverse;  
}

@keyframes example_4 {
  0%   {background-image:url('image/dzosoft_1.jpg'); left:0px; top:0px;}
  25%  {background-image:url('image/dzosoft_2.jpg'); left:200px; top:0px;}
  50%  {background-image:url('image/dzosoft_3.jpg'); left:200px; top:200px;}
  75%  {background-image:url('image/dzosoft_4.jpg'); left:0px; top:200px;}
  100% {background-image:url('image/dzosoft.jpg');   left:0px; top:0px;}
}
</style>
</head>
<body>
<div></div>
</body>
</html>
 

Example - 5 -

 
The animation-direction property specifies whether an animation should be played forwards,
backwards or in alternate cycles.
The following example uses the value "alternate" to make the animation run forwards first, then backwards
The animation-direction property can have the following values:
  • normal - The animation is played as normal (forwards). This is default
  • reverse - The animation is played in reverse direction (backwards)
  • alternate - The animation is played forwards first, then backwards
  • alternate-reverse - The animation is played backwards first, then forwards
    • The following example will run the animation in reverse direction (backwards):
    <!DOCTYPE html>
<html>
<head>
<style> 
 div{
  width: 50px;
  height: 50px;
  background-image:url('image/dzosoft.jpg'); 
  background-repeat: no-repeat;
  position: relative;
  animation-name: example_5;
  animation-duration: 4s;
  animation-direction: reverse;  
}

@keyframes example_5 {
  0%   {background-image:url('image/dzosoft.jpg');   left:0px; top:0px;}
  25%  {background-image:url('image/dzosoft_1.jpg'); left:200px; top:0px;}
  50%  {background-image:url('image/dzosoft_2.jpg'); left:200px; top:200px;}
  75%  {background-image:url('image/dzosoft_3.jpg'); left:0px; top:200px;}
  100% {background-image:url('image/dzosoft_4.jpg'); left:0px; top:0px;}
}
</style>
</head>
<body>
<div></div>
</body>
</html>
     

    Example - 6 -

     
    The animation-direction property specifies whether an animation should be played forwards, backwards or in alternate cycles.
    The following example uses the value "alternate-reverse" to make the animation run backwards first, then forwards:
     <!--
 <!DOCTYPE html>
<html>
<head>
<style> 
 div{
  width: 50px;
  height: 50px;
  background-image:url('image/dzosoft.jpg'); 
  background-repeat: no-repeat;
  position: relative;
  animation-name: example_6;
  animation-duration: 4s;
  animation-iteration-count: 2;
  animation-direction: alternate-reverse;  
}

@keyframes example_6 {
  0%   {background-image:url('image/dzosoft.jpg');   left:0px; top:0px;}
  25%  {background-image:url('image/dzosoft_1.jpg'); left:500px; top:0px;}
  50%  {background-image:url('image/dzosoft_2.jpg'); left:500px; top:100px;}
  75%  {background-image:url('image/dzosoft_3.jpg'); left:0px; top:100px;}
  100% {background-image:url('image/dzosoft_4.jpg'); left:0px; top:0px;}
}
</style>
</head>
<body>
<div></div>
</body>
</html>
     

    Example - 7 -

     
    The animation-timing-function property specifies the speed curve of the animation.
    It can have the following values:
    • ease - Specifies an animation with a slow start, then fast, then end slowly (this is default)
    • linear - Specifies an animation with the same speed from start to end
    • ease-in - Specifies an animation with a slow start
    • ease-out - Specifies an animation with a slow end
    • ease-in-out - Specifies an animation with a slow start and end
    • cubic-bezier(n,n,n,n) - Lets you define your own values in a cubic-bezier function
      • The following example shows some of the different speed curves that can be used
      <!DOCTYPE html>
<html>
<head>
<style> 
 div{
  width: 50px;
  height: 50px;
  background-color: white;
  font-weight: bold;
  position: relative;
  animation: move_dzo 5s infinite;
}

 .div_1{
  background-image:url('image/dzosoft.jpg'); 
  background-repeat: no-repeat;
  animation-timing-function: linear;
}
 .div_2{
  background-image:url('image/dzosoft_1.jpg'); 
  background-repeat: no-repeat;
  animation-timing-function: ease;
}
 .div_3{
  background-image:url('image/dzosoft_2.jpg'); 
  background-repeat: no-repeat;
  animation-timing-function: ease-in;
}
 .div_4{
  background-image:url('image/dzosoft_3.jpg'); 
  background-repeat: no-repeat;
  animation-timing-function: ease-out;
}
 .div_5{
  background-image:url('image/dzosoft_4.jpg'); 
  background-repeat: no-repeat;
  animation-timing-function: ease-in-out;
}

@keyframes move_dzo {
  from {left: 0px;}
  to {left: 500px;}
}
</style>
</head>
<body>
<div class="div_1"></div>
<div class="div_2"></div>
<div class="div_3"></div>
<div class="div_4"></div>
<div class="div_5"></div>
</body>
</html>
       

      Example - 8 -

       
      The animation-fill-mode property specifies a style for the target element when the animation is not playing
      (before it starts, after it ends, or both).
      The following example lets the <div> element retain the style values from the last keyframe
      when the animation ends:
      <!DOCTYPE html>
<html>
<head>
<style> 
 div{
  width: 50px;
  height: 50px;
  background-image:url('image/dzosoft_1.jpg'); 
  background-repeat: no-repeat;
  position: relative;
  animation-name: example_8;
  animation-duration: 3s;  
  animation-fill-mode: forwards;
}

@keyframes example_8 {
  from {top: 0px;}
  to {top: 400px; background-image:url('image/dzosoft_1.jpg');}
}
</style>
</head>
<body>
<div></div>
</body>
</html>
       

      Example - 9 -

       
      The following example lets the
      element get the style values set by the first keyframe before the animation starts
      (during the animation-delay period):
      Let the div element get the style values set by the first keyframe before the animation starts
      (during the animation-delay period)
      <!DOCTYPE html>
<html>
<head>
<style> 
 div{
  width: 50px;
  height: 50px;
  background-image:url('image/dzosoft_2.jpg'); 
  background-repeat: no-repeat;
  position: relative;
  animation-name: example_9;
  animation-duration: 3s;  
  animation-delay: 2s;
  animation-fill-mode: backwards;
}

@keyframes example_9 {
  from {top: 0px; background-image:url('image/dzosoft_2.jpg');}
  to {top: 200px;}
}
</style>
</head>
<body>
<div></div>
</body>
</html>
       

      Example - 10 -

       
      This example uses six of the animation properties
      <!DOCTYPE html>
<html>
<head>
<style> 
 div{
  width: 50px;
  height: 50px;
  background-image:url('image/dzosoft_3.jpg'); 
  background-repeat: no-repeat;
  position: relative;
  animation-name: example_10;
  animation-duration: 5s;
  animation-timing-function: linear;
  animation-delay: 2s;
  animation-iteration-count: infinite;
  animation-direction: alternate;
}

@keyframes example_10 {
  0%   {background-image:url('image/dzosoft.jpg');   left:0px; top:0px;}
  25%  {background-image:url('image/dzosoft_1.jpg'); left:200px; top:0px;}
  50%  {background-image:url('image/dzosoft_2.jpg'); left:200px; top:200px;}
  75%  {background-image:url('image/dzosoft_3.jpg'); left:0px; top:200px;}
  100% {background-image:url('image/dzosoft_4.jpg'); left:0px; top:0px;}
}
</style>
</head>
<body>
<div></div>
</body>
</html>
       

      Example - 11 -

       
      This example uses the shorthand animation property:
      <!DOCTYPE html>
<html>
<head>
<style> 
 div{
  width: 50px;
  height: 50px;
  background-image:url('image/dzosoft.jpg'); 
  background-repeat: no-repeat;
  position: relative;
  animation: example_11 5s linear 2s infinite alternate;
}

@keyframes example_11 {
  0%   {background-image:url('image/dzosoft.jpg');   left:0px; top:0px;}
  25%  {background-image:url('image/dzosoft_1.jpg'); left:300px; top:0px;}
  50%  {background-image:url('image/dzosoft_2.jpg'); left:300px; top:300px;}
  75%  {background-image:url('image/dzosoft_3.jpg'); left:0px; top:300px;}
  100% {background-image:url('image/dzosoft_4.jpg'); left:0px; top:0px;}
}
</style>
