javascript - When the bootstrap modal pops up, the mask layer is opaque under IE8

Question

I see that the source code of bootstrap has processing for lower versions of IE, but when I switch to IE8, the background is completely black

Answer 1

This problem should be that the css of the background is background:rgba(0,0,0,.5), but ie8 does not support rgba, which has a transparent background. You can define the css of the background separately for ie8, such as using a black transparent picture or ie For the filter method, it is recommended to use transparent images, as filters consume more resources
