Base

This template extends no other template and has a <!DOCTYPE html>.

How to extend ?

{% extends "[@CVTemplatesBundle](https://github.com/CVTemplatesBundle)/base.html.twig" %}

{# Your code here #}

See also Usage for the Symfony configuration.

head : is inside the <head>, it contains every other blocks and variables except the {% block body %};
favicon : is inside the {% block head %} and is empty;
preloads : is inside the {% block head %} and is empty;
importmap : is inside the {% block head %} and is empty;
stylesheets : is inside the {% block head %} and is empty;
javascripts : is inside the {% block head %} and is empty;
body : is inside the <body> and is empty.

Those HTML tags are rendered only if you define the corresponding variable in your template :

charset : <meta charset="{{ charset }}" />;
viewport : <meta name="viewport" content="{{ viewport }}" />;
baseUrl : <base href="{{ baseUrl }}" />;
htmlHeadTitle : <title>{{ htmlHeadTitle }}</title>;
metaDescription : <meta name="description" content="{{ metaDescription }}" />;
canonical : <link rel="canonical" href="{{ canonical }}" />.

This is always rendered :

app.request.locale : <html lang="{{ app.request.locale|replace({'_': '-'}) }}">, defined in Symfony configuration. The replace filter converts locales like en_GB into en-GB. It is necessary in order to pass W3C validation.
