背景颜色在 flex 容器中被截断答案

【问题标题】：Background color gets cut off in a flex container背景颜色在 flex 容器中被截断
【发布时间】：2018-01-18 00:42:33
【问题描述】：

我正在尝试使用绝对定位的弹性框制作表格。每行是一个标准 div，带有display: flex 每行中的每个项目都是弹性项目。请注意，任何地方都没有设置宽度。

为什么我的背景颜色这么乱。

我注意到如果行中有更多文本，背景会延伸得更远，并且位置是从背景计算的，这很好，除了背景不包括整行。

尝试显示：inline-flex 和 background-size: cover 无济于事

【解决方案1】：

使用width 而不是flex-basis，父级将增长以填充父级，而子级会从父级溢出。

【讨论】：

是的，但是为什么 flex 会失败？发布的代码实际上是我为绘制表格而创建的 tableViewer 对象的 sn-p。我希望 tableViewer 能够在标准页面内（内联、块等，与 flex 一样按预期工作）并且也在绝对设置中。弹性：0 0 200 像素；应该和宽度基本一样吧？
@RyanLee 我假设flex-basis 在页面上的布局与使用width 的布局不同，但我不知道为什么，我第一次看到这。我需要阅读规范，看看我是否能弄清楚。如果您认为解决方案没有帮助，我可以删除答案。
@@michael tbh 该解决方案没有帮助但无需删除:)
原来这个答案可能是正确的。解释在这里的浏览器错误部分：stackoverflow.com/a/34355447/3597276
@Michael_B 亲爱的，谢谢！已收藏。你是 flexbox 大师 :)

【解决方案2】：

您的主 div 容器是绝对定位的。

正如你提到的：“请注意，任何地方都没有设置宽度。”

在这种情况下，绝对定位的 div 的宽度将由其内容决定。

  border: 2px dashed red;

弹性项目溢出容器。但是由于背景颜色是在容器上设置的，所以颜色以容器结尾。

一种解决方案是在绝对定位的容器上设置宽度：

div[style*="absolute"] {
  border: 2px dashed red;
  width: 1000px; /* the sum of flex item widths */
 /* or width: 100% */
 /* or left: 0; right: 0; */
}

* {
  box-sizing: border-box;
}

<div style="z-index: 3; position: absolute; top: 50px; left: 50%; transform: translateX(-50%);">

div[style*="absolute"] > div:nth-child(odd) > div {

【讨论】：

谢谢 Michael_B 但我应该提到在这个绝对设置中我特别不想设置外部容器宽度。我只是希望它根据其内部增长，因为我将动态添加和删除列，并且不希望每次都重新计算外部宽度，因此是 flexbox。
"在这种情况下，绝对定位的 div 的宽度将由其内容决定。"那么具体设置宽度是什么？因为它停止的方式看起来很随意。
哈哈找到答案了！原来它是一个 2 岁的错误.....stackoverflow.com/questions/34352140/… 在浏览器错误下
我发布了第二个解决方案，不需要在容器上设置宽度。
我不得不从每个 sn-p 中删除第二个示例，因为答案超出了字符数限制。
