我有一个包含Bootstrap Carousel的Bootstrap模式。我需要在Carousel中激活的幻灯片才能获得焦点。我试图覆盖轮廓样式以使焦点更加明显(特别是在Edge中)。我可以成功聚焦(codepen只会在第一张幻灯片上执行此操作以进行演示),如果我不覆盖大纲,则可以看到图像上的默认浏览器大纲。但是,当我试图覆盖轮廓时,它会完全消失。

如何成功覆盖大纲?
答案 0 :(得分:1)
根据我所看到的情况,如果您定位:focus
项,我不确定您是否需要.active
。 overflow: hidden
确实隐藏了轮廓。
请改为尝试:
.carousel-inner .item.active {
border: #00bfff solid 5px;
}

我遇到其他堆叠帖后我能够解决这个问题。这非常难以搜索! styling the outline border with outer overflow set to hidden
我选择的解决方案是该页面上两条建议的组合:
.carousel-inner .item.active:focus
{
outline: 2px solid #00bfff;
outline-offset: -2px;
}
/* FIX FOR EDGE: When Edge impliments outline-offset will want to delete
this block. But until then this is the best method
to allow a noticeable outline for accessibility
*/
.carousel-inner .item.active:focus::after
{
content: "";
height: 99.19%;
outline: 2px solid #00bfff;
position: absolute;
top: 2px;
left: 2px;
width: 99.19%;
z-index: 99999;
}
