Twig Append Content to Block
Shortcut to append/prepend content to blocks with few content, e.g. a pagetitle
base.html.twig
...<title>{% block title %}MyApp{% endblock %}</title>...template extending base layout
{% extends '::base.html.twig' %}{% block title 'Page1 - '~parent() %} {# prepend #}{% block title parent()~' - Page1' %} {# append #}
Calling parent() in the child template works, but each child must explicitly accept inheritance from the parent. You can also choose to enforce this inheritance by using a sub-block instead.
inner.html.twig
{% block css %} a { color: #fff; } body { background: #f00; } {% block css_custom %}{% endblock css_custom %}{% endblock css %}myWidget.html.twig
{% block css_custom %} div a { color: #777; }{% endblock css_custom %}
