I am working on custom theme and the parent theme is blank.I have added the below code in default_head_block.xml
<page xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:noNamespaceSchemaLocation="urn:magento:framework:View/Layout/etc/page_configuration.xsd">
<head>
<css src="css/styles-m.css" />
<css src="css/styles-l.css" media="screen and (min-width: 768px)"/>
<css src="css/print.css" media="print" />
</head>
But in view source of browser custom.css loads before styles-l.css how can i fix it ?
