I need to override CSS/JS that will override the styling and I need it to load the last part among other CSS files link like:
<head>
<title>Home page</title>
<link rel="stylesheet" type="text/css" media="all" href="http://mage2.dev/pub/static/frontend/Magento/luma/en_US/mage/calendar.css" />
<link rel="stylesheet" type="text/css" media="all" href="http://mage2.dev/pub/static/frontend/Magento/luma/en_US/css/styles-m.css" />
<link rel="stylesheet" type="text/css" media="screen and (min-width: 768px)" href="http://mage2.dev/pub/static/frontend/Magento/luma/en_US/css/styles-l.css" />
<link rel="stylesheet" type="text/css" media="print" href="http://mage2.dev/pub/static/frontend/Magento/luma/en_US/css/print.css" />
<link rel="icon" type="image/x-icon" href="http://mage2.dev/pub/static/frontend/Magento/luma/en_US/Magento_Theme/favicon.ico" />
<link rel="shortcut icon" type="image/x-icon" href="http://mage2.dev/pub/static/frontend/Magento/luma/en_US/Magento_Theme/favicon.ico" />
<script type="text/javascript" src="http://mage2.dev/pub/static/frontend/Magento/luma/en_US/requirejs/require.js"></script>
<script type="text/javascript" src="http://mage2.dev/pub/static/frontend/Magento/luma/en_US/mage/requirejs/mixins.js"></script>
<script type="text/javascript" src="http://mage2.dev/pub/static/_requirejs/frontend/Magento/luma/en_US/requirejs-config.js"></script>
<!-- ADD MY CUSTOM CSS/JSS LOAD AT THE LAST -->
<link rel="stylesheet" type="text/css" media="all" href="http://mage2.dev/pub/static/frontend/Magento/luma/en_US/css/OVERRIDE.CSS">
<script type="text/javascript" src="http://mage2.dev/pub/static/frontend/Magento/luma/en_US/js/OVERRIDE.JS"></script>
</head>
I found this post (How to add a custom CSS file in Magento 2) but it's not working for me.
(Posted it in magento forum but got no reply: link here)
Any help would be much appreciated.
