如何在保持淡入淡出动画的同时禁用淡出 Bootstrap 5 Modal？

Question

我知道如何通过移除父项 div 中的“淡入淡出”class 来移除模态框的淡入淡出动画。但是我需要在去掉淡出动画的同时保留淡入动画。

有什么想法吗？

您可以通过将以下 CSS 放入您的自定义 CSS 文件中使其工作。

.modal.fade {
    transition: opacity 0s linear 0s;
}
.modal.fade.show {
    transition: opacity 0.15s linear 0s;
}

这是工作代码片段，请查看一次。

.modal.fade {
    transition: opacity 0s linear 0s;
}
.modal.fade.show {
    transition: opacity 0.15s linear 0s;
}
