In magento 1.x, I can add the css files into the head using helper like below code.
<reference name="head">
<action method="addCss"><stylesheet helper="module/helperclass/helperfunction"/></action>
</reference>
But cannot do this on Magento 2.
So now, I added this code <link rel="stylesheet" type="text/css" media="all" href="<?php echo $_helper->getCSSFile()?>">
into "after.body.start" container.
Anyone know how can I add custom template file into <head>
?
