BrowserBlast is a lightweight and fully customisable script to display a warning for users of IE7 and below to let them know their browser isn’t supported anymore.

Include the browserBlast.min.js file in your document and place the following into the head of your document to initiate the plugin. Make sure you've also included jQuery.

<script type="text/javascript" src="browserBlast.min.js"></script>
	<script>
		browserBlast();
</script>

browserBlast({
	devMode: false, // Show warning on all browsers for testing
	supportedIE: '8', // Supported IE version, warning will display on older browsers
	message: 'Hey! Your browser is unsupported. Please <a href='http://		browsehappy.com' target='_blank'>upgrade</a> for the best experience.' // Set custom message
});
