滾動區域內絕對定位的div不延伸超出視口

Question

說明

當與overflow:auto或overflow:scroll含div包含一系列display:inline-block元件，使得它推動含量足夠寬，以創建一個滾動條，隨後position:absolute帶有left:0;right:0;的元素無法填滿可滾動視口，因此滾動包含的div也會滾動絕對定位的元素。

Fiddle（以下簡稱「結果」窗口，你得到一個水平滾動條的寬度位置，然後滾動左，右觀察.row-cover div的背景未能延伸到滾動區域）

問題

我正在尋找一個CSS唯一的解決方案。爲了用一個元素「掩蓋」.row，我應該做什麼樣的CSS更改，以使其下面的內容「被遮蓋」？

HTML

<div class="outer-outer-container"> 
    <div class="outer-container">

EDIT

更新以包括外外容器具有overflow:hidden禁用body滾動

Answer 1

設置外容器div爲display:table。
