To control the repetition of an image in the background, the CSS background-repeat property is used.

<html>
   <head>
      <style>
         body{
            background-image: url("https://app.3schools.in/logo.png");
            background-repeat:repeat;
         }
      </style>
   </head>
   <body>
      <p>This is a paragraph.</p>
   </body>
</html>
