css - 嵌套 flex 盒元素中的文本被截断

Question

我想要截断 Flexbox 元素中的文本。这完全没问题。但如果这个 Flexbox 元素包裹在另一个 Flexbox 元素中，它就会崩溃。有没有办法让一切变得流畅并且不会破裂？

我做了一支笔，你可以看到它在这里断了: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 {

  overflow: hidden;
  text-overflow: ellipsis;

Answer 1

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%; */
}
