我有一个组件，其中 Bootstrap 4 自动扩展列换行到另一行。具有“text-truncate”类和长文本的元素的存在导致 Chrome 将列元素垂直堆叠在它所属的行下。
在下面的代码片段中，带有 ID 的 <div>，如果子 problem-div 元素应用了 Boostrap 4 类 <span> 并且该元素包含冗长的文本，text-truncate 将换行并消耗整行。删除 text-truncate 类，problem-div 元素将消耗其容器中第一行未使用的部分。
就目前而言，我可以获得子内容的截断功能 - 或者我可以让父列填充其父列第一行的未使用部分，但不能同时使用这两个列。 如何同时获得两者？

</body>最佳答案
当 flex 元素包含带有应截断文本的子元素时，布局可能会被破坏。
我的第一个解决方案是将 min-width: 0 添加到 problem-div 的父级(看看 css 技巧文章:https://css-tricks.com/flexbox-truncated-text/):
img {
width: 16px;
height: 16px;
}
label {
margin: 0;
font-weight: 600;
}
.form-text {
margin: 0;
}
#problem-div {
background-color: #e0FFFF;
}<link href="https://maxcdn.bootstrapcdn.com/bootstrap/4.0.0/css/bootstrap.min.css" rel="stylesheet" />

</body>另一种解决方案是将 overflow: hidden 添加到 problem-div 的父级:
img {
width: 16px;
height: 16px;
}
label {
margin: 0;
font-weight: 600;
}
.form-text {
margin: 0;
}
#problem-div {
background-color: #e0FFFF;

<body class="container-fluid">
