所以基本上我使用的是React引导模型。
我正在使用React和react-bootstrap组件。我实现了它，但是当我打开它时，背景不是半透明的（不透明度0.5），而是黑色的。

你也可以看到。当我打开模态时，背景变黑了，你几乎看不到后面的任何东西。
像这样使用模态

较暗的背景是由以下原因造成的：

.modal-backdrop.show {
  opacity: var(--bs-backdrop-opacity);
}

首先，试试这个：

.modal-backdrop.show {
  opacity: 1;
}

这应该会完全移除不透明度。如果没有，可能是因为您在不透明度的上方套用了不透明度，所以才会如此暗。请检查您第二次套用不透明度的位置。

所提供的屏幕截图表明，在打开模态时，DOM中有多个.modal-backdrop.show元素。
这可能是由以下任何原因引起的（我怀疑该列表是否详尽）：

嵌套的情态动词（情态动词中的情态动词）
重复的模式id s（运行时存在于DOM中）
错误的模态实现，在关闭时没有删除.modal-backdrop，导致它在每次后续打开时都有+1个背景。

您没有提供足够的代码来确定原因（或重现问题），所以我只能提供一个隐藏问题的解决方案，而不修复错误源：

.modal-backdrop:not(#_) ~ .modal-backdrop,
body:not(.modal-open) .modal-backdrop {
  display: none;
}

我不推荐这样做，（这是在掩盖灰尘）。相反，你应该找到并修复bug源。

所以我对@鹿的答案做了一些操作，得出了这个解。

.modal-backdrop
{
    --bs-backdrop-bg: rgb(0 0 0 / 30%) !important;
}

这对我有用。
