具有剩余宽度、省略号和新行上的一些内容的 Flexbox 列表

Question

我正在努力学习 flexbox，但我很难理解这个概念。我想创建一个电子邮件列表，其中每个项目都是一个 flexbox 容器（见下文）。

规则：

标签是可选的，但如果显示，它会直接显示在名称旁边。
日期始终存在，宽度变化
人名填余space。如果它变得太大，它就会被截断。
名称和标签之间的space总是5px
邮件主题换行显示，也被截断

  padding: 0;

li {

Answer 1

所以我对你的代码做了这个：

通过将 flex-wrap: wrap 添加到 li
[=，使您的 flexbox 变成 wrap 73=]
强制 subject 到下一行，告诉它在行中使用 全部可用宽度 给它 flex-basis: 100%
添加margin-left: auto将date放在最右端。
要完成它，您可以将这些样式添加到 name 和 subject 以获得 省略号 效果：
```
  white-space: nowrap;
  overflow: hidden;
```
还在name中添加了max-width: 50%以调整第一行。

参见下面的演示：

.container {
  width: 350px;
  background-color: #FFF;
}
html {
  font-family: 'Nunito Sans', sans-serif;
}
ul {
  list-style-type: none;
  padding: 0;
  margin: 0;
}
li {
  display: flex;
  flex-wrap: wrap;
  flex-direction: row;
  align-items: baseline;
  padding: 20px;
  border-bottom: 1px solid #ccc;
}
.name {
  font-size: 16px;
  font-weight: bold;
  text-overflow: ellipsis;
  white-space: nowrap;
  overflow: hidden;
  max-width: 50%;
}
.tag {
  margin-left: 5px;
  font-size: 10px;
  font-weight: bold;
  background-color: #EFEFEF;
  padding: 3px 5px;
  border-radius: 3px;
  text-transform: uppercase;
}
.subject {
  font-size: 15px;
  font-weight: 300;
  color: #888;
  text-overflow: ellipsis;
  white-space: nowrap;
  overflow: hidden;
  flex-basis: 100%;
}
.date {
  margin-left: auto;
}

建议:

您应该编辑标记并为包含 name、tag 和 date 的第一行创建一个 wrapper更好的设计（您可以删除上面使用的 untidy max-width: 50%）- 请参见下面的演示：

.container {
  width: 350px;
  background-color: #FFF;
}
html {
  font-family: 'Nunito Sans', sans-serif;
}
ul {
  list-style-type: none;
  padding: 0;
  margin: 0;
}
li {
  display: flex;
  flex-wrap: wrap;
  flex-direction: row;
  align-items: baseline;
  padding: 20px;
  border-bottom: 1px solid #ccc;
}
.name {
  font-size: 16px;
  font-weight: bold;
  text-overflow: ellipsis;
  white-space: nowrap;
  overflow: hidden;
}
.tag {
  margin-left: 5px;
  font-size: 10px;
  font-weight: bold;
  background-color: #EFEFEF;
  padding: 3px 5px;
  border-radius: 3px;
  text-transform: uppercase;
}
.subject {
  font-size: 15px;
  font-weight: 300;
  color: #888;
  text-overflow: ellipsis;
  white-space: nowrap;
  overflow: hidden;
  flex-basis: 100%;
}
.date {
  margin-left: auto;
}
.header {
  display: flex;
  width: 100%;
}

Answer 2

只是对 kukkuz 优秀答案的扩展。

在这里，我们获得了相同的结果，但无需更改标记。（有些更棘手，但有时您可以更改标记）。

您真正需要的是摆脱 flex-wrap 并将所有前 3 个元素设置在一行中。一种替代方法是将 subject 元素设置在 flex 容器之外，将其定位为绝对。其余的修改只是为了恢复损坏的布局。

.container {
  width: 350px;
  background-color: #FFF;
}
html {
  font-family: 'Nunito Sans', sans-serif;
}
ul {
  list-style-type: none;
  padding: 0;
  margin: 0;
}
li {
  display: flex;
  flex-direction: row;
  align-items: baseline;
  padding: 20px 0px 40px 0px;
  margin: 0px 20px;
  border-bottom: 1px solid #ccc;
  position: relative;
}
.name {
  font-size: 16px;
  font-weight: bold;
  text-overflow: ellipsis;
  white-space: nowrap;
  overflow: hidden;
}
.tag {
  margin-left: 5px;
  font-size: 10px;
  font-weight: bold;
  background-color: #EFEFEF;
  padding: 3px 5px;
  border-radius: 3px;
  text-transform: uppercase;
}
.subject {
  font-size: 15px;
  font-weight: 300;
  color: #888;
  text-overflow: ellipsis;
  white-space: nowrap;
  overflow: hidden;
  flex-basis: 100%;
  position: absolute;
  bottom: 20px;
  max-width: 100%;
}
.date {
  margin-left: auto;
}
.header {
  display: flex;
  width: 100%;
}
