如何在方向列 flexbox 子项中截断字符串 [英] How to truncate string inside a direction column flexbox child

问题描述

我翻阅了csstricks的文章，https://css-tricks.com/flexbox-截断文本/

我的问题是当 .flex-parent 具有 flex-direction: column; 属性时如何使其工作.

感谢您的帮助！

解决方案

这实际上只是重新排列一些属性的问题，但这个答案自然取决于项目的需要.

这里的要点是，如果您希望它成为一列，那么您在 .flex-parent 中包含的每个顶级元素本质上都会在设置为列方向时显示为.因此，它的右边没有任何东西可以截断.

所以本质上，如果您希望顶级元素成为一列并截断其中的内容，那么实现它的一种方法是将它们都包含在同一行"或 .flex-child 中.然后该行是您可以识别 justify 和 aligning 属性的地方.

.flex-parent {显示:弹性；弹性方向:列；填充:10px；边距:30px 0;}.flex-子{显示:弹性；对齐内容:间隔；对齐项目:居中；}.long-and-truncated-with-child-corrected {弹性:1；最小宽度:0；/* 或一些值 */}.long-and-truncated-with-child-corrected h2 {空白:nowrap；溢出:隐藏；文本溢出:省略号；}.short-and-fixed >div {宽度:30px；高度:30px；边框半径:10px；背景:浅绿色；显示:inline-flex；}/*非必需品*/身体 {填充:40px；}h2{字体大小:1rem；字体粗细:正常；}.flex-父{背景:RGBA(0,0,0,0.1)；}

<div class="flex-child long-and-truncated-with-child-corrected"><h2>这是一个<em>长字符串</em>可以截断，谢谢.如果字符串是 <b>REALLY</b>截断的<div class="flex-child short-and-fixed"><div></div><div></div><div></div>

I went over the article from csstricks, https://css-tricks.com/flexbox-truncated-text/

My question how to make it work when the .flex-parent has flex-direction: column; property.

Thanks for help!

解决方案

This really is just a matter of rearranging some properties, but naturally this answer depends on the projects needs.

Takeaways here are, if you want it to be a column, by nature every top-level element you include in the .flex-parent, when it's set to column direction, will display as such. Therefore, there will be nothing to the right of it to truncate with.

So essentially, if you want top-level elements to be a column AND truncate content inside of it, then one way of accomplishing it is by including both of them in the same 'row' or .flex-child. Then the row is where you could identify the justify and aligning properties.

.flex-parent {
  display: flex;
  flex-direction: column;
  padding: 10px;
  margin: 30px 0;
}
.flex-child {
  display: flex;
  justify-content: space-between;
  align-items: center;
}
.long-and-truncated-with-child-corrected {
  flex: 1;
  min-width: 0; /* or some value */
}
.long-and-truncated-with-child-corrected h2 {
    white-space: nowrap;
    overflow: hidden;
    text-overflow: ellipsis;
}
.short-and-fixed > div {
    width: 30px;
    height: 30px;
    border-radius: 10px;
    background: lightgreen;
    display: inline-flex;
}

/*nonessentials*/
body {
  padding: 40px;
}
h2 {
  font-size: 1rem;
  font-weight: normal;
}
.flex-parent {
  background: rgba(0,0,0,0.1);
}

<div class="flex-parent">

  <div class="flex-child long-and-truncated-with-child-corrected">
    <h2>This is a <em>long string</em> that is OK to truncate please and thank you. Some more text to demonstrate, if the string is <b>REALLY</b> truncated</h2>
    <div class="flex-child short-and-fixed">
      <div></div>
      <div></div>
      <div></div>
    </div>
  </div>

</div>
