php inline style to my contact send form - php

Question

Here is what I got thus far. Where would I an my inline code? I also have the html page where the form is coded yet I have it linked to this php page. The form works great just wanted to add some style to it for a client.
<?php
// define variables and set to empty values
$name_error = $email_error = $phone_error = $subject_error = "";
$name = $email = $phone = $message = $subject = $success = "";
//form is submitted with POST method
if ($_SERVER["REQUEST_METHOD"] == "POST") {
if (empty($_POST["name"])) {
$name_error = "Name is required";
} else {
$name = test_input($_POST["name"]);
// check if name only contains letters and whitespace
if (!preg_match("/^[a-zA-Z ]*$/",$name)) {
$name_error = "Only letters and white space allowed";
}
}
if (empty($_POST["email"])) {
$email_error = "Email is required";
} else {
$email = test_input($_POST["email"]);
// check if e-mail address is well-formed
if (!filter_var($email, FILTER_VALIDATE_EMAIL)) {
$email_error = "Invalid email format";
}
}
if (empty($_POST["phone"])) {
$phone_error = "Phone is required";
} else {
$phone = test_input($_POST["phone"]);
// check if phone number is well-formed
if (!preg_match("/^(\d[\s-]?)?[\(\[\s-]{0,2}?\d{3}[\)\]\s-]{0,2}?\d{3} [\s-]?\d{4}$/i",$phone)) {
$phone_error = "Invalid phone number";
}
}
if (empty($_POST["subject"])) {
$subject_error = "Subject is required";
} else {
$subject = test_input($_POST["subject"]);
// check if subject is proper text form
if (!preg_match("/^[a-zA-Z ]*$/",$subject)) {
$subject_error = "Invalid URL";
}
}
if (empty($_POST["message"])) {
$message = "";
} else {
$message = test_input($_POST["message"]);
}
if ($name_error == '' and $email_error == '' and $phone_error == '' and $subject_error == '' ){
$message_body = '';
unset($_POST['submit']);
foreach ($_POST as $key => $value){
$message_body .= "$key: $value\n";
}
// sends message to an email address specified.
$to = 'email#gmail.com';
$subject = 'Contact Form Submit';
if (mail($to, $subject, $name, $message)){
$success = "Message sent, thank you for contacting us!";
$name = $email = $phone = $message = $subject = '';
}
}
}
function test_input($data) {
$data = trim($data);
$data = stripslashes($data);
$data = htmlspecialchars($data);
return $data;
}
any help would be appreciated!

First, i think you have an error in your mail() function call.
The right way to send an email using this function is:
mail($to, $subject, $message, $headers);
The $headers parameter is optional, but if you need to send stylesh emails, you'll need this.
An example of these headers:
$headers = "From: $name<$email>".PHP_EOL;
$headers .= "MIME-Version: 1.0".PHP_EOL;
$headers .= "X-Mailer:PHP/".phpversion()."".PHP_EOL;
$headers .= "Content-Type: text/html; charset=utf-8".PHP_EOL;
With these headers you are saying to the email client that you are sending html content, then, in your $message you can put some tags like:
$message = "<strong>Name:</strong> $name<br /><strong>Lorem ipsum</strong><br /><hr />Lorem ipsum";
Note: if you want to include some images, just use the tag, but using publics urls in the src, like this:
<img src="http://www.yoursite.com/emails/email-header.jpg" />
