造型引导转盘指标 [英] Styling bootstrap carousel indicators

问题描述

你好，我试图让默认的引导程序轮播指标变得非常细的黄线，如下图所示。

Hello I'm trying to get the default bootstrap carousel indicators to be very thin yellow lines stuck att he bottom as shown below.

我让他们在页面底部，但我似乎无法将它们更改为矩形或更改它们的颜色。

I got them to be at the bottom of the page but I can't seem to change them into rectangles or change their color.

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%;
    }

推荐答案

请注意，宽度并不是完全准确的，因为我只是把它做成了33％。

Something like this? Note that the width is not totally accurate because I just made it 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;
}
