Bootstrap 模态正在侧边栏内呈现

Question

我对这个不断出现在我身边 div 区域内的模式感到迷惑，我在 bootstrp5 文档和任何在线论坛上都没有找到任何关于它的信息。

根据 bootstrap 文档 (https://getbootstrap.com/docs/5.0/components/modal/)，我只需要它以页面为中心呈现，淡入淡出效果影响所有背景。但是我还没有找到任何方法让它工作...

我正在使用 bootstrap 5 (custom.css) 和以下前端代码：

Answer 1

您将 width 添加到 @media screen and (min-width: 768px) 部分的 .show。你不应该这样做。如果你想改变模式的大小，你可以设置 .modal-dialog class

的宽度

Answer 2

除了@MehriZareie 所说的，您还将 .show 的 left 属性设置为 0。

所以模态框没有出现在侧边栏的“内部”，您只是将它设置为与侧边栏相同的左坐标和宽度。

Bootstrap 模态正在侧边栏内呈现
