如何删除默认的引导程序 3 轮播控件背景渐变

Question

我很确定这是我需要修改的代码，但由于某种原因，我无法让渐变在IE中消失。我要他们完全消失！

.carousel-control {
text-shadow: none;
opacity: 1;
filter: alpha(opacity=100)
}
.carousel-control.left {
background-image: -webkit-gradient(linear, 0 top, 100% top, from(rgba(0,0,0,0.5)), to(rgba(0,0,0,0.0001)));
background-image: -webkit-linear-gradient(left, color-stop(rgba(0,0,0,0.5) 0), color-stop(rgba(0,0,0,0.0001) 100%));
background-image: -moz-linear-gradient(left, rgba(0,0,0,0.5) 0, rgba(0,0,0,0.0001) 100%);
background-image: linear-gradient(to right, rgba(0,0,0,0.5) 0, rgba(0,0,0,0.0001) 100%);
background-repeat: repeat-x;
filter:progid:DXImageTransform.Microsoft.gradient(startColorstr='#80000000', endColorstr='#00000000', GradientType=1)
}
.carousel-control.right {
background-image: -webkit-gradient(linear, 0 top, 100% top, from(rgba(0,0,0,0.0001)), to(rgba(0,0,0,0.5)));
background-image: -webkit-linear-gradient(left, color-stop(rgba(0,0,0,0.0001) 0), color-stop(rgba(0,0,0,0.5) 100%));
background-image: -moz-linear-gradient(left, rgba(0,0,0,0.0001) 0, rgba(0,0,0,0.5) 100%);
background-image: linear-gradient(to right, rgba(0,0,0,0.0001) 0, rgba(0,0,0,0.5) 100%);
background-repeat: repeat-x;
filter:progid:DXImageTransform.Microsoft.gradient(startColorstr='#00000000', endColorstr='#80000000', GradientType=1)
}
.carousel-control:hover, .carousel-control:focus {
opacity: 1;
filter: alpha(opacity=100)
}

Answer 1

.carousel-control.left, .carousel-control.right {
    background-image: none
}

Answer 2

IE有一个奇怪的过滤器，当尝试在IE9中修复它时，它有效（应该适用于所有人）：

.carousel-control.left, .carousel-control.right{ 
    background: none !important;
    filter: none !important;
    progid:none !important;
}

Answer 3

我注意到，当您单击它时，除非您添加以下内容，否则它也会有这个烦人的虚线框：

总而言之，这使按钮变得漂亮：

.carousel-control.left, .carousel-control.right {
  background: none !important;
  filter: progid: none !important;
  outline: 0;
 }
.carousel .carousel-control {
  visibility: hidden;
}
.carousel:hover .carousel-control {
  visibility: visible;
}

Answer 4

有专门的mixin用于重置IE梯度（Bootstrap 3）。

屁股：

.carousel-control {
  &.left, &.right {
    background-image: none;
    @include reset-filter();
  }
}

Answer 5

.carousel-control {
        opacity:100;
    }

为我工作。希望这可以帮助某人。
