I'm trying add custom css file for my module namely Magento_Hello in magento2. In the module I've created new page and trying to add new custom css to that page.
Here is what I have done in app/code/Magento/Hello/hello_index_index.xml. ('hello' is the frontName of my module)
<?xml version="1.0" encoding="UTF-8"?>
<page xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:noNamespaceSchemaLocation="../../../../../../../lib/internal/Magento/Framework/View/Layout/etc/page_configuration.xsd">
<head>
<title>Hello World</title>
</head>
<body>
<referenceContainer name="content">
<block class="Magento\Hello\Block\Hello" name="hello" template="success.phtml"/>
</referenceContainer>
</body>
<referenceBlock name="head">
<block class="Magento\Theme\Block\Html\Head\Css" name="magento-hello-css">
<arguments>
<argument name="file" xsi:type="string">Magento_Hello::css/custom.css</argument>
</arguments>
</block>
</referenceBlock>
</page>
I'have added the css here app\code\Magento\Hello\View\frontend\web\css\custom.css
But I'm getting the error in system.log which says the 'magento-hello-css' element cannot be added as child to 'head', because the latter doesn't exist [] []
What I'm doing wrong? Can anyone help here?
