Boostrap4 li列表橫向

Boostrap3 li元素橫向：

<ul class="nav navbar-nav list-inline">
  <li class="list-inline-item"><a class="social-icon text-xs-center" target="_blank" href="#">FB</a></li>
  <li class="list-inline-item"><a class="social-icon text-xs-center" target="_blank" href="#">G+</a></li>
  <li class="list-inline-item"><a class="social-icon text-xs-center" target="_blank" href="#">T</li>
</ul>

Boostrap4 以上方法不行，得如下方法：

<ul class="list-inline">
	<li class="list-inline-item"><img src="http://static.open-open.com/news/uploadImg/20160727/20160727083501_753.jpg" width="100px" </li>
	<li class="list-inline-item"><img src="http://static.open-open.com/news/uploadImg/20160727/20160727083501_753.jpg" width="100px" </li>
	<li class="list-inline-item"><img src="http://static.open-open.com/news/uploadImg/20160727/20160727083501_753.jpg" width="100px" </li>
	<li class="list-inline-item"><img src="http://static.open-open.com/news/uploadImg/20160727/20160727083501_753.jpg" width="100px" </li>
</ul>
