Bootstrap 4 - change the carousel indicators into dots
提问by Lance Shi
I am using Bootstrap 4 Beta 2 version to do a carousel. The code looks like below:
我正在使用 Bootstrap 4 Beta 2 版本进行轮播。代码如下所示：
<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>
</ol>
And the carousel indicator show as lines:
轮播指示器显示为线条：
Is there a way I can change the indicators into dots instead of lines? I would assume it is an bootstrap option but I didn't find that relevant document. Do I need to write custom css for that?
有没有办法可以将指标更改为点而不是线？我认为这是一个引导程序选项，但我没有找到相关文档。我需要为此编写自定义 css 吗？

Yes, I think you need to write custom CSS for doing lines into dots.
You just need to override two properties (widthand height) and add a new one, border-radius, to .carousel-indicators li.
Make widthand heightvalues equal eg: 10pxeach and give a border-radiusof 100%.
是的，我认为您需要编写自定义 CSS 来将线变成点。
您只需要覆盖两个属性 ( widthand height) 并添加一个新属性border-radius, 到.carousel-indicators li。
制作width和height值等于例如：10px每给予border-radius的100%。
.carousel-indicators li {
width: 10px;
height: 10px;
border-radius: 100%;
}

You just need to change the icon path in case you have one, using the inspect element you can get the class name. I used Mozilla to get the class name and then I used two svg icons for changing the default icons to custom icons.
如果您有图标路径，您只需要更改图标路径，使用检查元素可以获得类名。我使用 Mozilla 获取类名，然后使用两个 svg 图标将默认图标更改为自定义图标。
.carousel-control-prev-icon {
background-image: url("images/carousel/back.svg");
}
.carousel-control-next-icon {
background-image: url("images/carousel/next.svg");
}

I had to include .carousel for it to work properly.
我必须包含 .carousel 才能正常工作。
.carousel .carousel-indicators li {
width: 10px;
height: 10px;
border-radius: 100%;
}
