Why my ui-li button's touch field has cut?

I made div-ul-li-a button on html. But when I click it, it react on only left field. It isn't react on right field. Why is it?

제가 만든 코드에서, div - ul - li - a 형식의 버튼이 왼쪽 부분만 반응하고 오른쪽 부분은 반응하지 않아요.

This is html file for show on web. I use PyCharm tool to use Flask and Python. ( html file in Pycharm ) Pycharm에서 Flask를 통해 html 파일을 웹으로 보여주고 있습니다.
