css - 面包屑会收缩以掩盖内容

我希望完成一些缩小的面包屑内容（希望没有js ...但我可以满足于香草js）

我有数量未知的物品需要放入面包屑之类的东西（不可导航）

我想要的是


在这里，活动项目始终是可读的，并且如果项目足够少，则它们都是可读的（即，非活动选项卡将其宽度缩放为适合可用宽度，确保活动项目完全可见后再离开）Ive按照教程进行了学习非常接近（但我不知道如何缩放）

我得到的是

/* BREADCRUMBS.CSS */
ul.breadcrumb {
  list-style: none;
  width: 460px;
  height: 40px;
  border-radius: 2px;
  border: solid 1px #d2d2d2;
}

ul.breadcrumb li {
  float: left;
  border-top: 1px solid #d2d2d2;
  border-bottom: 1px solid #d2d2d2;
  font: 14px Roboto, "Helvetica Neue", sans-serif;
}
ul.breadcrumb li:first-of-type {
  border-left: 1px solid #d2d2d2;
}

ul.breadcrumb li span.inner {
  overflow: hidden;
  direction: rtl;
  white-space: nowrap;
  /* keeps everything on one line */
  width: 100%;
}

ul.breadcrumb li {
  color: #4a4a4a;
  font-weight: bold;
  text-decoration: none;
  padding: 10px 0 10px 40px;
  background: #F5F5F5;
  position: relative;
  display: block;
  min-width: 10px;
  float: left;
  padding-right: 1em;
}

ul.breadcrumb li.active {

  min-width: 150px;

}

ul.breadcrumb li::after {

  border-top: 22px solid transparent;
  /* Go big on the size, and let overflow hide */

}

Example 1. Works fine with a couple of items
<ul class="breadcrumb ng-star-inserted">
  <li class="active ng-star-inserted"><span class="inner">CLEAN DEVICE</span></li>
  <li class="pending ng-star-inserted"><span class="inner">Reading</span></li>
  <li class="pending ng-star-inserted"><span class="inner">Reading</span></li>
</ul>

<hr/>

How Do i make inactive items shrink (and hide text as needed) so they all fit on the same row? while keeping the active tabs text visible
<ul class="breadcrumb ng-star-inserted">
  <li class="active ng-star-inserted"><span class="inner">CLEAN DEVICE</span></li>
  <li class="pending ng-star-inserted"><span class="inner">Reading</span></li>
  <li class="pending ng-star-inserted"><span class="inner">Reading</span></li>
    <li class="pending ng-star-inserted"><span class="inner">Reading</span></li>
  <li class="pending ng-star-inserted"><span class="inner">Reading</span></li>
</ul>

（顺便说一句，我不喜欢这里的任何概念（即，如果使用ul以外的元素更容易））...基本上在css上太糟糕了:(

最佳答案

您可以尝试使用flexbox：


将display: flex添加到ul（可以选择覆盖其默认填充），
将flex: 0 0 auto添加到第一个和最后一个li（这是一种简写形式，它表示弹性项目不应增长或收缩，而只能采用其自动宽度），
并有选择地也删除第一个min-width的li。


请参见下面的演示：

  padding: 0; /* added */
}
