如何删除默认的Bootstrap 3传送带控制背景渐变？
我敢肯定，这是我需要修改的代码，但由于某种原因，我不能让梯度消失在IE浏览器。 我希望他们完全消失！
.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) } .carousel-control.left, .carousel-control.right { background-image: none }
IE浏览器有一个奇怪的filter，并试图修复它在IE9（应该适用于所有）时工作：
.carousel-control.left, .carousel-control.right{ background: none !important; filter: progid:none !important;> }
我注意到，当你点击它的时候，也会有这个恼人的虚线框，除非你添加这个：
总而言之，这使button美丽：
.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; }
有专门的混音器来重置IE渐变（Bootstrap 3）。
上海社会科学院：
.carousel-control { &.left, &.right { background-image: none; @include reset-filter(); } }
.carousel-control { opacity:100; }
为我工作。 希望这可以帮助别人。
