这是Bootstrap中关于轮播图的代码 :
<div id="carouselExampleIndicators" class="carousel slide" data-bs-ride="carousel">
<div class="carousel-indicators">
<button type="button" data-bs-target="#carouselExampleIndicators" data-bs-slide-to="0" class="active" aria-current="true" aria-label="Slide 1"></button>
<button type="button" data-bs-target="#carouselExampleIndicators" data-bs-slide-to="1" aria-label="Slide 2"></button>
<button type="button" data-bs-target="#carouselExampleIndicators" data-bs-slide-to="2" aria-label="Slide 3"></button>
</div>
<div class="carousel-inner">
<div class="carousel-item active">
<img src="自己的图片路径" class="d-block w-100" alt="...">
</div>
<div class="carousel-item">
<img src="自己的图片路径" class="d-block w-100" alt="...">
</div>
<div class="carousel-item">
<img src="自己的图片路径" class="d-block w-100" alt="...">
</div>
</div>
<button class="carousel-control-prev" type="button" data-bs-target="#carouselExampleIndicators" data-bs-slide="prev">
<span class="carousel-control-prev-icon" aria-hidden="true"></span>
<span class="visually-hidden">Previous</span>
</button>
<button class="carousel-control-next" type="button" data-bs-target="#carouselExampleIndicators" data-bs-slide="next">
<span class="carousel-control-next-icon" aria-hidden="true"></span>
<span class="visually-hidden">Next</span>
</button>
</div>
原始焦点效果如图:
自定义之后如图:
方法 :
1、找到自己的 bootstrap-5.1.1-dist\css\bootstrap.css
2、查找 .carousel-indicators
3、在自己css中加入以下代码 (可根据bootstrap.css找到的 .carousel-indicators [data-bs-target] 相关图片位置的代码自行调整)
.carousel-indicators [data-bs-target]{
margin: 0 5px;
background: url(./img/zhu.png) left no-repeat; /*图片路径,我这边为相对路径*/
}
4、完成 (注意自定义的图片需要设置小些,大概像素值30-40左右)
