I try to add external css/javascript to the head. I added this to my theme under Magento_Theme\layout\default_head_blocks.xml:
<?xml version="1.0"?>
<page xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:noNamespaceSchemaLocation="urn:magento:framework:View/Layout/etc/page_configuration.xsd">
<head>
<meta name="viewport" content="width=device-width, initial-scale=1, shrink-to-fit=no"/>
<link rel="stylesheet" href="https://stackpath.bootstrapcdn.com/bootstrap/4.4.1/css/bootstrap.min.css"
integrity="sha384-Vkoo8x4CGsO3+Hhxv8T/Q5PaXtkKtu6ug5TOeNV6gBiFeWPGFN9MuhOf23Q9Ifjh"
crossorigin="anonymous"
src_type="url"
type="text/css"
>
<script src="https://stackpath.bootstrapcdn.com/bootstrap/4.4.1/js/bootstrap.min.js"
integrity="sha384-wfSDF2E50Y2D1uUdj0O3uMBJnjuUD4Ih7YwaYd1iqfktj0Uod8GCExl3Og8ifwB6"
crossorigin="anonymous"
src_type="url"
>
</script>
</head>
</page>
But it does not load the files and they are not showing in the sourcecode.
I also removed the attributes integrity
and crossorigin
but it still fails. I executed grunt clean
to clear the cache.
