Yes,you can do it using an extra tag. Call it as a slider for now.

So, now if you click on the slider will move to and fro.

Here is code attached.

var tabs = document.getElementsByClassName('Tab');

Array.prototype.forEach.call(tabs, function(tab) {
	tab.addEventListener('click', setActiveClass);
});

function setActiveClass(evt) {
	Array.prototype.forEach.call(tabs, function(tab) {
		tab.classList.remove('active');
	});
	
	evt.currentTarget.classList.add('active');
}

.Tabs {
	position: relative;
	background-color: #fff;
	margin: 0;
	padding: 0;
	list-style: none;
}

.Tabs:after {
		content: ' ';
		display: table;
		clear: both;
	}

.description_tab {
		float: left;
		width: 33.333%;
		text-align: center;
	}

.description_tab:first-child.active ~ .slider {
			left: 0;
		}

.description_tab:nth-child(2).active ~ .slider {
			left: 33.333%;
		}

.slider {
		position: absolute;
		bottom: 0;
		left: 0;
		width: 33.333%;
		height: 4px;
		background-color: #4A66F4;
		transition: left .25s;
	}

.Tab {
	font-family: 'Roboto Slab';
}

.Tab > a {
		display: block;
		padding: 10px 12px;
		text-decoration: none;
		color: #666;
		transition: color .15s;
	}

.Tab.active > a {
			color: #222;
		}

.Tab:hover > a {
			color: #222;
		}
