具有Intro.js透明的Bootstrap 4模态

Question

以下example显示了一个引导程序模式，该模式在intro.js的第二步中被激活。不幸的是，我不知道如何透明地覆盖intro.js，因此您可以看到模式。此外，我想像在example中一样添加进度条。希望有人可以帮助我。

Answer 1

您可以将模态放在叠加层的前面，这样按钮仍会突出显示，但是您可以在简介控件后面看到模态。这需要将Bootstrap的模式z-index设置为高于introjs叠加层，并覆盖introjs modal-fixer样式。

.modal{
  z-index:1000000;
}

.introjs-fixParent.modal{
  z-index:10000000 !important;
}

该脚本只是缺少setOption（'showProgress'，true）
