Draw SVG lightning bolts on to any element, creating a flash effect.
Just add the library and call the flash function:
<html style="height: 100%">
<head>
<script src="https://raw.githubusercontent.com/guggero/light-it-up/master/index.js"></script>
</head>
<body>
<button onclick="flash({duration: 500})">Flash for 0.5s</button>
</body>
</html>Have a look at the demo too
{
element: document.getElementById('foo'), // element to render into, default: document.body
duration: 1000, // duration of flash effect in milliseconds, default 800
zIndex: 9999, // CSS property 'z-index' of the inserted <div>, default 1000
colorFlash: '#ffffff', // color of the flash, default rgba(255, 255, 255, 1)
colorBlur: '#333333', // color of the blur effect, default rgba(192, 192, 255, 1)
