我该怎么做？

请帮助我

Answer 1

您可以使用此代码

附加 CSS ：

.count{
width: 15px;
height: 15px;
border-radius: 15px;
display: -webkit-flex;
display: flex;
-webkit-align-items: center;
align-items: center;
-webkit-justify-content: center;
justify-content: center;
position: absolute;
top: 15px;
left: 60px;
background: #ff420f;
}

最后在 HTML 中：

<li class="nav-item position-relative">
<a class="nav-link" href="#"><img src="img/basket.jpg" class="pl-lg-4 pr-2">
<span class="badge badge-primary count">5</span >
<span class="ml-2 d-lg-none d-xl-inline">Koszyk</span></a>
</li>

不要忘记在li.nav-item中添加类.position-relative
