        </title>
    </head>
      
    <body>
        <h1 style="color: green">
            GeeksforGeeks
        </h1>
          
        <b>DOM Style textTransform Property</b>
          
        <p>
            The textTransform property can be used
            to capitalize, uppercase or lowercase
            the text.
        </p>
