Styling

The component can be further styled after the props have been defined by overriding the default css styling. The best way to do this is to use a class differenciator or the id="" prop and then scope your global css with this class/id.

/* The followinf classes can be used to style the splitter, see demos*/

.splitpanes {
	background-color: #f8f8f8;
}

.splitpanes__splitter {
	background-color: #ccc;
	position: relative;
}
.splitpanes__splitter:before {
	content: '';
	position: absolute;
	left: 0;
	top: 0;
	transition: opacity 0.4s;
	background-color: rgba(255, 0, 0, 0.3);
	opacity: 0;
	z-index: 1;
}
.splitpanes__splitter:hover:before {
