有一個清單和一個評論欄位。評論欄位為 fixed 到頁面底部。當清單很長時，會套用頁面滾動。
我希望清單底部始終與評論欄位頂部保持一定的垂直距離。當然，我可以將margin-bottom 屬性套用到.meaning 類別（它會形成清單），但是如果註解欄位包含2 或3 行文字（即，對於設定邊距來說太高了）。
因此，在我看來，將 margin-top 設定為 comment 欄位更有意義。但是，可能由於評論欄位的 z-index: 1 屬性，margin-top 也不起作用。
這裡是 JS Bin，以防萬一。

<li class="sentence-en">Lorem Ipsum is simply dummy text of the printing and typesetting industry. Lorem Ipsum has been the industry's standard dummy text ever since the 1500s, when an unknown printer took a galley of type and scrambled it to make a type specimen book. It has survived not only five centuries, but also the leap into electronic typesetting, remaining essentially unchanged. It was popularised in the 1960s with the release of Letraset sheets containing Lorem Ipsum passages, and more recently with desktop publishing software like Aldus PageMaker including versions of Lorem Ipsum</li>
<li class="sentence-de">Contrary to popular belief, Lorem Ipsum is not simply random text. It has roots in a piece of classical Latin literature from 45 BC, making it over 2000 years old. Richard McClintock, a Latin professor at Hampden-Sydney College in Virginia, looked up one of the more obscure Latin words, consectetur, from a Lorem Ipsum passage, and going through the cites of the word in classical literature, discovered the undoubtable source. Lorem Ipsum comes from sections 1.10.32 and 1.10.33 of "de Finibus Bonorum et Malorum" (The Extremes of Good and Evil) by Cicero, written in 45 BC. This book is a treatise on the theory of ethics, very popular during the Renaissance. The first line of Lorem Ipsum, "Lorem ipsum dolor sit amet..", comes from a line in section 1.10.32.</li>
