Passing html div classes in php mail form

[hatefulcrawdad]

I have the following code in my php mail form:

print '<div class="email-err"><h3>Error!</h3><p>Please enter a valid email address</p></div>';
} elseif (empty($emailName)) {
echo '<div class="email-err"><h3>Error!</h3><p>Please enter your name</p></div>';
} elseif (empty($emailSubject)) {
echo '<div class="email-err"><h3>Error!</h3><p>Please enter a subject</p></div>';
} elseif (empty($_POST['Message'])) {
echo '<div class="email-err"><h3>Error!</h3><p>Please enter a message</p></div>';
} else {
if (!empty($emailFrom)) {
$emailHeaders = 'FROM: <[email protected]>';
}
   

 

Is that the proper way to pass divs and classes through php? I am trying to target them with css and nothing is working, so I'm guessing it is not. People have been helpful on here before, so I'm hopeful someone knows this.

That would output valid html. So yeah.

 

Where are you placing the css definitions?

I am putting them in the css file attached to this page.

Nevermind, I was a dummy and didn't realize where the stuff was being outputted. So I was calling the wrong id in the css. Fixed, thanks. Your comments sparked me to take a look closer.
