如何对齐相对容器内的css固定元素？

我试图在一个可滚动的容器中放置一个固定的“标题”......因此，当您滚动时，标题始终位于顶部......对于某些虚假未知原因，它始终将标题置于实际窗口顶部而不是位置：相对容器。如何对齐相对容器内的css固定元素？

下面是一个例子：

谁能解释：1）为什么出现这种情况，和2）我如何能实现我的目标是什么？

谢谢。

固定的位置总是与您的视口有关，所以这已经阻止您做你想做的事。

我能想到的唯一建议是改变HTML的结构，使标题在带有foobar的容器的外部。如果它在外面，则可以使用绝对或相对，并使用上/左移动到您想要的位置。

所以我真正做到这一点是为了将容器外的标题移动到容器外，并将标题置于相对位置。就这样。

position: fixed总是相视（浏览器窗口）。

我想你可以通过在.headerposition: absolute并从.container移动height: 50px和overflow: auto到.body实现自己的目标。您将需要更改height，因为标题不再是其中的一部分。

.outer-container { 
 
    height: 500px; 
 
    background: blue; 
 
    display: block; 
 
} 
 
.offsetinator { 
 
    padding-top: 100px; 
 
} 
 
.inner-container { 
 
    width: 100%; 
 
} 
 
.container { 
 
    position: relative; 
 
    background: teal; 
 
    width: 100%; 
 
} 
 
.header { 
 
    position: absolute; 
 
    top: 0; 
 
    background: orange; 
 
} 
 
.body { 
 
    overflow: auto; 
 
    height: 50px; 
 
} 
 
.row { 
 
    background: green; 
 
} 
 
.row span { 
 
    background: gray; 
 
    padding: 0 25px; 
 
}
<div class="outer-container"> 
 
    <div class="offsetinator"> 
 
    <div class="inner-container"> 
 
     <div class="container"> 
 
     <div class="header"> 
 
      <div class="row">

      <span>thing2</span>

  1. position: fixed总是忽略盒模型一路攀升到文档体。

  2. 不幸的是，但可能是出于很好的理由，没有办法将固定的相对于父元素（除了主体）相对定位。解决办法：取消固定的风格和滚动添加到您的<div class="body">
