我发现{backdrop: false}可以使模态的叠加层透明。

但是它可以防止在模态外点击关闭模态。

问题： 如何通过close modal启用click outside of the modal，同时，模式的叠加层保持透明？

Answer 1

只需将opacity:0添加到背景元素，然后移除backdrop:false

即可

.modal-backdrop {
  opacity:0!important;
}

Answer 2

添加以下样式

.modal-backdrop.in {
    filter: alpha(opacity=0); // For IE
    opacity: 0; // For all other browsers
}

此外不需要背景：现在是假的。

但有一点我想提一下，虽然你可以在背景中看到什么，但是在模态关闭之前它不会被点击或访问。

Bootstrap3，具有透明覆盖的模态，但也可以通过单击模态外部来关闭它
