Asset Tags

Sometimes a plugin wants to add some CSS and JavaScript to your theme, for example, the Cookie Consent plugin. It adds a cookie consent popup to all pages, so that users can agree to the cookie policy of your website.

There are two Twig-tags, that allow plugins to add JavaScript and CSS. Please make sure that you add these tags to your theme, because otherwise, the plugins won't work:

{{ assets.renderCSS() }}
{{ assets.renderJS() }}

It is recommended to add the CSS tag after all your css files, and before the closing <head> tag. It is also a good practice in Twig to wrap your ressources in a block-tag. You can read more about this in the Twig chapter.

<html>
 <head>
  <title>title</title>
  ....
  ....
  {% block stylesheets %}
    <link rel="stylesheet" href="{{ base_url }}/themes/mytheme/css/style.css" />

    {{ assets.renderCSS() }}

  {% endblock %}
 </head>

The same for JavaScript: It is recommended to place all JavaScript at the end of the page before the closing <body> tag. And you should wrap all your JavaScript in a block-element, too:

<body>
  ...
  {{ content }}
  ...
  ...

  {% block javascripts %}

   <script src="{{ base_url }}/themes/yourtheme/js/my.js"></script>

   {{ assets.renderJS() }}

 {% endblock %}     
</body>
