html - 为什么我的 Bootstrap 拉伸(stretch)链接会延伸出几层？

Question

我正在尝试拉伸(stretch)我的嵌套 div 的链接，但它甚至包括父级。我只需要 listItem 可点击，但这使得整个卡片 div 可点击。

每the Bootstrap docs (以及 absolute positioning 的基本规则)，拉伸(stretch)链接适用于具有非静态定位的最近元素。您可以将 position-relative 类放在父级上以实现此目的。

我还用父段落上的 lead 类替换了您的内联字体大小样式。只是不要使用内联样式，尤其是当您的样式库提供 typography classes 时为此。
