<h2>Submit Button</h2>
<p>The <strong>input type="submit"</strong> defines a button for submitting form data to a form-handler:</p>
<form action="/action_page.php">
<label for="fname">First name:</label><br>
<input type="text" id="fname" name="fname" value="John"><br>
<label for="lname">Last name:</label><br>
<input type="text" id="lname" name="lname" value="Doe"><br><br>
<input type="submit" value="Submit">
</form>
<p>If you click "Submit", the form-data will be sent to a page called "/action_page.php".</p>
