我想在图像激活时更改
img-circle
的背景颜色。<div id="myCarousel" class="carousel slide">
<div class="carousel-buttons">
<div class="col-sm-4 text-center">
<a class="text-center " data-target="#myCarousel" data-slide-to="0" href="#">
<div class="img-circle center-block">
<img class="carousel-icons-img" src="image/icon-1-student.svg" >
</div>
</a>
</div>
