像素和百分比宽度div并排 [英] Pixel and percentage width divs side-by-side

问题描述

我发现了很多类似的问题，并尝试了几种解决方案（包括一些所谓的圣杯 CSS布局），但是它们并不能完全满足我的需要。

I've found a lot of similar questions, and tried out several solutions (including some of the so-called "holy grail" CSS layouts), but they don't quite do what I need.

我有一个包含div（一个CSS包含块），其ID为 right 。在它的左侧，我想要一个固定宽度的div（分隔条，但是它的用途并不重要； id splitpane ）；在右侧，填充其余的空间，另一个div（下面的id 右框）。

I have a containing div (a CSS containing block) with id right. Inside it on the left side, I want a fixed-width div (a splitter bar, but it doesn't matter what it's being used for; id splitpane); on the right, filling the rest of the space, another div (id right-box below).

I尝试使两个内部divs 显示：内联块（使用 vertical-align：top ），将左一个设置为 width：3px ，但是无法将右设置为100％-3px。我也尝试过使用 float：left / margin-left：-100％ / margin-left：3px 技巧，但有相同的问题：100％加3px会使包含父元素的块溢出，并弹出滚动条。 （当然，问题本身不是滚动条；我可以使用 overflow：hidden 删除它，但是右边的内容将被截断。）

I've tried making the two inner divs display: inline-block (with vertical-align: top), setting the left one to width: 3px, but then there's no way to set the right to have width 100% - 3px. I've also tried using the float: left/margin-left: -100%/margin-left: 3px trick, but it has the same problem: the 100% plus the 3px overflows the parent containing block and causes a scroll bar to pop up. (Of course, it's not the scroll bar per se that's the problem; I could use overflow: hidden to remove it, but then content on the right would be truncated.)

当前，我在正确的div上使用 width：99.5％，但这是一个可怕的技巧（并且受到溢出取决于屏幕宽度）。看起来有点像这样：

Currently I'm using width: 99.5% for the right div, but that's a terrible hack (and is subject to overflow depending on screen width). It looks a bit like this:

<div id="right"><div id="splitpane"></div><div id="right-box">
  ...
</div></div>

使用CSS如下（浮动版本，但内联块版本相似）：

With CSS as follows (float version, but the inline-block version is similar):

#right {
  display: inline-block;
  vertical-align: top;
  height: 100%;
  width: 85%;  /* this is part of a larger div */
}
#right-box {
  width: 99.5%; /* stupid hack; actually want 100% - 3px for splitter */
  height: 100%;
}
#splitpane {
  float: left;
  width: 3px;
  height: 100%;
  background: white;
  border-left: solid gray 1px;
  border-right: solid gray 1px;
  cursor: e-resize;
}

是否有可能这样做？这是针对内部应用程序的。因此，解决方案仅需要在Firefox 3中运行（但是，如果它们特定于FF3，则最好是因为该解决方案符合标准，而其他浏览器则不是，不是因为它仅使用Firefox）代码）。

Is it even possible to do this? This is for an internal app., so solutions only need to work in Firefox 3 (if they are specific to FF3, though, preferably it's because the solution is standards-compliant but other browsers aren't, not because it's using Firefox-only code).

推荐答案

这是可能的。由于块级元素会自动扩展以占据任何剩余的水平空间，因此可以在具有所需宽度的未清除浮动元素旁边使用块级元素。

This is possible. Because block level elements automatically expand to take up any remaining horizontal space, you can utilise a block level element next to an uncleared floated element with your desired width.

<style type="text/css">
    div {
        height: 100px;
    }
    #container {
        width: 100%;
    }
    #left {
        background: #FF0;
    }
    #splitpane {
        position: relative;
        float: right;
        background: #000;
        width: 3px;
    }
</style>

<div id="container">
    <div id="splitpane"></div>
    <div id="left"></div>
</div>
