Last Updated : 14 Aug, 2020

The Dot Loading animation can be used to enhance the user interface of a website, it can be added while the website loads. This animation can be easily created using HTML and CSS.

HTML Code: In this section we will create the basic structure of the dot loader using a div tag which will have some span tags inside of it.

<!DOCTYPE html> 
<html lang="en"> 
<head> 
  <meta charset="UTF-8"> 
  <meta name="viewport"
        content="width=device-width, 
                 initial-scale=1.0"> 
  <title>Dots Loading Animation</title> 
</head> 
<style> 
    
<body> 
  <div class="loader"> 
    <span></span> 
    <span ></span> 
    <span ></span> 
    <span ></span> 
    <span></span> 
    <span></span> 
  </div> 
</body> 
</html> 

CSS Code: In this section first we will create the dots structure using some basic CSS properties and then in order to create the animation we will use @keyframes rule and use the transformX() function to produce the desired effect.

<style> 
body{ 
  margin: 0; 
  padding: 0; 
 } 
  
 .loader{ 
   position: absolute; 
   top: 50%; 
   left: 50%; 
   transform: translate(-50%, -50%); 
   display: flex; 
   align-items: center; 
     
 } 
 /* Creating the dots */ 
 span{ 
   height: 25px; 
   width: 25px; 
   margin-right: 10px; 
   border-radius: 50%; 
   background-color: green; 
   animation: loading 1s linear infinite; 
 } 
 /* Creating the loading animation*/ 
 @keyframes loading { 
   0%{ 
    transform: translateX(0); 
   } 
   25%{ 
    transform: translateX(15px); 
   } 
   50%{ 
    transform: translateX(-15px); 
   } 
   100%{ 
    transform: translateX(0); 
   } 
     
 } 
  
span:nth-child(1){ 
  animation-delay: 0.1s; 
} 
span:nth-child(2){ 
  animation-delay: 0.2s; 
} 
span:nth-child(3){ 
  animation-delay: 0.3s; 
} 
span:nth-child(4){ 
  animation-delay: 0.4s; 
} 
span:nth-child(5){ 
  animation-delay: 0.5s; 
} 
</style>
