这是我想出的：
HTML
<a class="navbar-brand" href="#">
<div class="eye">

CSS
.eye {
position: absolute;
background-color: black;
width: 65px;
height: 65px;
top: 0;
left: 17px;
}
.eye svg {
margin: 8px 8px 8px 8px;
fill: white;
}
.navbar-brand {
float: left;
height: 50px;
padding: 15px 50px;
font-size: 18px;
line-height: 20px;
}
还有另一种方法吗？因为我觉得我的方式是错的。
答案 0 :(得分：1)
以下是基于您发布的图片的示例。绝大多数只是造型和最少量的结构调整，主要是为了抵消SVG下的内容，所以根本没有重叠。
请参阅工作代码段。
