这是设计师一直在处理的一个令人沮丧的问题。诀窍是你需要在CSS中的BODY和HTML上设置高度为100%。

html,body {
    height:100%;
}

这段看似毫无意义的代码是为了向浏览器定义100%的含义。的确令人沮丧，但这是最简单的方法。

如前所述，flexbox是最简单的。 如。

#main{ display: flex; align-items:center;}

这将使所有子元素对齐到父元素的中心。

经过长时间的寻找和尝试，没有什么能解决我的问题

style = "height:100%;"

关于儿童div

对于父母应用这个

.parent {
    display: flex;
    flex-direction: column;
}

此外，我使用bootstrap，这并没有腐败的响应为我。

我的解决方案:

$(window).resize(function() {
   $('#div_to_occupy_the_rest').height(
        $(window).height() - $('#div_to_occupy_the_rest').offset().top
    );
});

下面的代码提供了设置滚动div的最小高度的能力，并通过使用flex使其具有其父div的100%高度。

CSS:

.main {
  display: flex;
  flex-direction: column;
}

.scroll {
  overflow: auto;
  flex: 1 0 50px;
}

HTML:

<div class="main">
  <div class="scroll">

如果你不介意导航div在意外的短内容div事件中被剪辑，至少有一个简单的方法:

#main {
position: relative;
}

#main #navigation {
position: absolute;
top: 0;
left: 0;
bottom: 0;
width: 10em; /* or whatever */
}

#main #content {
margin: 0;
margin-left: 10em; /* or whatever width you set for #navigation */
}

除此之外，还有假柱技术。
