How Can I Add A Class, Id Or Attribute To A Twig Include?

31 July 2018 - 1 answer

I am working on a project that uses twig. Each page uses

{% extends "_layouts/_master" %}

Inside the _layouts/master there is a body tag

<body class="{% block bodyClass %}{% endblock %}">

Can I add a class to the body tag from a page that is using the include?

You can override parent block (defined in _layouts/_master) in child template (the one that extends parent). In your child template add this:

{% extends "_layouts/_master" %}
{% block bodyClass %}css-body-class another-css-body-class{% endblock %}

You can also include content of parent block and append something to it:

{% extends "_layouts/_master" %}
{% block bodyClass %}{{parent()}} css-body-class another-css-body-class{% endblock %}

You can read more in twig documentation for extends.
