I got very strange issue with Magento 2 and custom css files. I'm trying to add custom css to the head
<head>
<link src="js/bundle.js"/>
<css src="css/main.css" />
</head>
After I flush cache, do deploy and than I see all css files in
pub\static\frontend\Sleepz\md\en_US\css
except of main.css
I tried to deploy in developer/default mode, did Di compile, guess everything. What I do wrong?
