样式化引导轮播指示器

Question

我试图让默认的引导轮播指示器成为非常细的黄线，卡在底部，如下所示。

我让它们位于页面底部，但我似乎无法将它们更改为矩形或更改颜色。

HTML

 <ol class="carousel-indicators">
    <li data-target="#myCarousel" data-slide-to="0" class="active"></li>
    <li data-target="#myCarousel" data-slide-to="1"></li>
    <li data-target="#myCarousel" data-slide-to="2"></li>
    <li data-target="#myCarousel" data-slide-to="3"></li>
</ol>

CSS

 .carousel-indicators {
    margin: 0px;
    height: 0px;
}

.carousel-indicators ol {
    width: 100%;
}

.carousel-indicators li {
    height: 3px !important;
    border-radius: 0px !important;
    width: 25%;
}

Answer 1

是这样的吗？请注意，宽度并不完全准确，因为我刚刚将其设置为 33%。

 .item img {
  width: 100%;
  height: auto
}

.carousel {
  position: relative;
  width: 200px;
  height: 100px;
}

ol.carousel-indicators {
  position: absolute;
  bottom: 0;
  margin: 0;
  left: 0;
  right: 0;
  width: auto;
}

ol.carousel-indicators li,
ol.carousel-indicators li.active {
  float: left;
  width: 33%;
  height: 10px;
  margin: 0;
  border-radius: 0;
  border: 0;
  background: transparent;
}

ol.carousel-indicators li.active {
  background: yellow;
}

伟大的CSS！我用它来设计半白的球指示器和黄色的活动指示器。

 ol.carousel-indicators {
     position: absolute;
     bottom: 5px;
     margin: 0;
     left: 0;
     right: 0;
     width: auto;
}

ol.carousel-indicators li, ol.carousel-indicators li.active {
     width: 1rem;
     height: 1rem;
     margin: 0;
     border-radius: 50%;
     border: 0;
     background: transparent;
}

ol.carousel-indicators li {
     background: rgba(255,255,255,0.39);
     margin-left: .5rem;
     margin-right: .5rem;
}

ol.carousel-indicators li.active {
     background: yellow;
}
