嵌套 flexbox 项目中的截断文本

Question

我想截断 flexbox 项目中的文本。这完全没问题。但是，如果这个 flexbox 项目被另一个 flexbox 项目包裹，它就会破坏。有没有什么办法可以让一切都变得流畅不爆裂？

我做了一支笔，你看到它在这里断了：http://codepen.io/anon/pen/apJYaN

.accordeon {
  width: 300px;
  background-color: #eeeeee;
}

.accordeon__row {
  /* if you remove this, then it works */
  display: flex;
}

.accordeon__row-label {
  flex-basis: 30%;
}

.accordeon__row-content {
  list-style-type: none;
  padding-left: 0;
  margin-bottom: 0;
  margin-top: 0;
}

.accordeon__row-item {
  display: flex;
}

.accordeon__row-value {
  white-space: nowrap;
  overflow: hidden;
  text-overflow: ellipsis;
}

Answer 1

不确定您究竟希望它看起来像什么，但您可以通过使用网格布局而不是 flexbox 来实现它。所以没有任何东西从父容器中脱离出来。

以下是完成网格布局的方法：

.col-1 {width: 8.33%;}
.col-2 {width: 16.66%;}
.col-3 {width: 25%;}
.col-4 {width: 33.33%;}
.col-5 {width: 41.66%;}
.col-6 {width: 50%;}
.col-7 {width: 58.33%;}
.col-8 {width: 66.66%;}
.col-9 {width: 75%;}
.col-10 {width: 83.33%;}
.col-11 {width: 91.66%;}
.col-12 {width: 100%;}

[class*="col-"] {
    float: left;
    padding: 0;

}

.row {
    width: 300px;
    margin: 0 auto;

}

.row::after {
    content: "";
    clear: both;
    display: block;
}

然后给每个 accordeon__row 行 class 并给每个 accordeon__row-item col-12 class。这样可以确保该项目始终包含在父行中。您可以尝试为项目分配不同的 col-n classes。

Answer 2

您可以添加以下行：

.accordeon__row-content {
  ...
  min-width: 0; /* https://www.w3.org/TR/css-flexbox-1/#min-size-auto */
}

并调整这一行：

.accordeon__row-label {
  flex: 0 0 30%; /* fixed width flex item, previously flex-basis: 30%; */
}
