HTML/PHP Contact Form

On my message section I would like to to go down to the second line once the users writing approaches the end of the box. Instead, it stays on a single line continuously forever. How can I fix this?

<font color="#ffffff" font face="Arial" font size="2">Frank Technology</font>

<form method="POST" action="mailer.php">

<font color="#ffffff" font face="Arial" font size="2">Name: (Required)</font><br>

         <input type="text" name="name" size="25"><br>

         <br>

<font color="#ffffff" font face="Arial" font size="2">Email: (Required)</font><br>

         <input type="text" name="email" size="25"><br>

         <br>

         <br>

         <input type="submit" value="Submit" name="submit">

<?php


if(isset($_POST['submit'])) { 

$to = "john.frank@msn.com";

$subject = "Frank Technology";

$name_field = $_POST['name']; 

$email_field = $_POST['email'];

$message = $_POST['message']; 

  

$body = "From: $name_field\n E-Mail: $email_field\n Message:\n $message"; 

  

echo "Thank you for contacting us. We will get back to you shortly.";

mail($to, $subject, $body);

} else { 

echo "blarg!";

}

?>
