I am trying to send an email from my PHP script. The email is send automatically through cron jobs. But when i got the email the bootstrap design has broken off. I am linking the following jquery and bootstrap files;
<script src="http://code.jquery.com/jquery-1.11.1.min.js"></script>
<link rel='stylesheet prefetch' href='https://maxcdn.bootstrapcdn.com/font-awesome/4.7.0/css/font-awesome.min.css'>
<link rel='stylesheet prefetch' href='https://maxcdn.bootstrapcdn.com/bootstrap/3.3.4/css/bootstrap.min.css'>
I guess gmail will block the external css. Which is the best way for this to work?
