CSS form border formatting inside PHP file - php

Question

I'm trying to embed some CSS into my PHP file. How can I properly add my CSS so that each called form will be rendered inside a black border? This is what I tried so far.
while ($ratings = mysql_fetch_array($q))
{
//This outputs the doctors's name
echo "Doctor's name:" . $ratings['doctor_name'] ."<br />";
// Retrieve the id of the doctor which was posted on
$id = $_POST['id'];
echo "<style> form { border-style: solid; border-color: #ffffff}";
//This outputs a textarea for the user to submit comments
echo "<b>Your Experience: </b>";
echo "<form method='post' action='review_doctors.php'>
<textarea name='body'></textarea>
<input type='submit' name='submit' value='Send'/>
<input type='hidden' name='id' value='$ratings[id]' />
</style>
</form>
";
echo "<br />";
}

As mentioned in the comments: "The style tag should only include styles".
?>
<style>
form {
border: 3px solid black;
}
</style>
<?php
while ($ratings = mysql_fetch_array($q)) {
echo "<form>...</form>"
}
If you would like to reuse styles you can put them in their own file and then include them on each page:
?>
<link rel="stylesheet" type="text/css" href="/path/to/mystyle.css">
<?php
// ...
