HTML5 form validation

HTML5 has ability for form validation. Putting  'required' in input field shows that the field  has to be inputted before form submission. Using placholder to get a hint in input field.  For email fiedl, you have to enter *@-.-.  to be accepted.  in url field, I put  the pattern to only accept text starting with http:// or https:/. For number field, I put min and max for number range.
    <form action=" " method="post">
        <label for="name">Name:</label>
        <input type="text" name="name" required placeholder="Name" />
        <br />
        <label for="email">Email:</label>
        <input type="email" name="email" required placeholder="" />
       <br />
        <label for="website">Website:</label>
        <input type="url" name="website"  required pattern="https?://.+" />
<br />
        <label for="number">Number:</label>
        <input type="number" name="number" min="0" max="10" step="2" required placeholder="Even num < 10">
<br />
        <label for="range">Range:</label>
        <input type="range" name="range" min="0" max="10" step="2" />
<br />
        <label for="message">Message:</label>
        <textarea name="message" required></textarea>
    <br />
        <input type="submit" value="Send Message" />
