 I was recently doing some work on a site hosted on [Pantheon](http://getpantheon.com) and came across an issue, for which part of the suggested fix was to ensure that the `$base_url` variable was explicitly defined within settings.php (this is also best practice on all Drupal sites).
 
 The way that was recommended was by using a `switch()` function based on Pantheon's environment variable. For example:
-{% endblock %}
 
-{% block content %}
 ```language-php
 switch ($_SERVER['PANTHEON_ENVIRONMENT']) {
   case 'dev':

 ```
 
 The environment specific files are also committed into Git and pushed to Pantheon, and are then included automatically on each environment.
