Answer 1

你需要两个规则：

• max-width您的.card元素(因为没有定义宽度CSS将不知道在哪里中断您的长单词(或overflow: hidden;使.card宽度不再取决于长单词长度
• word-wrap: break-word;告诉浏览器破坏一个字

---

.card {
    max-width: 100%;
}
.card-text {
    word-wrap: break-word;
}

---

.card {
  overflow: hidden;
}
.card-block {
  word-wrap: break-word;
}

简单：

/* For screens above: 576px */

Answer 3

还要考虑这一点(对于 URL 等(; 从文档中：

对于较长的内容，可以添加 .text-truncate 类以使用省略号截断文本。需要显示：内联块或显示：块。

Answer 4

为了将来参考，这也将起作用：

.card-text {
  overflow-wrap: anywhere;
  word-wrap: break-word;
  word-break: normal;
  hyphens: auto;
}
