Customize verify.php

[masilli]

Sorry if this has already been answered. I couln't find it.

I can customize, and style with css the verify.php to show up a message after reCAPTCHA is sucessful... but what about when it fails?

How to costumize with html+css the message highlighted below?

if (!$resp->is_valid) {
    // What happens when the CAPTCHA was entered incorrectly
    die ("The reCAPTCHA wasn't entered correctly. Go back and try it again." .
         "(reCAPTCHA said: " . $resp->error . ")");
  } else {
    // Your code here to handle a successful verification
  }
