	</div>
	<div class="sticks"></div>
</label>


    <script>
      document.querySelector('.sticks').addEventListener('click', function (e) {
	e.stopPropagation();
	e.preventDefault();
	//document.querySelector('.input').value = '';
	document.querySelector('.input-container').blur();
});
      //# sourceURL=pen.js
    </script>

Tiếp đến là chèn đoạn css nữa là xong:
