最近有在图片右上角加X（删除）的需求，记录一下。CSS样式如下：
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<meta name="viewport" content="width=device-width, initial-scale=1.0">
<meta http-equiv="X-UA-Compatible" content="ie=edge">
<title>Document</title>
<style>
.img-box {
margin: 10px;
display: inline-block;
position: relative;
}
.myimage {
width: 80px;
height: 80px;
}
.del-icon {
position: absolute;
width: 15px;
height: 15px;
border: 1px solid red;
border-radius: 50%;
top: -13px;
right: -15px;
transform: rotate(45deg);
}
.del-icon::before {
display: block;
position: absolute;
content: "";
width: 10px;
height: 2px;
background-color: red;
top: 50%;
left: 50%;
transform: translate3d(-50%, -50%, 0);
}
.del-icon::after {
display: block;
position: absolute;
content: "";
width: 2px;
height: 10px;
background-color: red;
top: 50%;
left: 50%;
transform: translate3d(-50%, -50%, 0);
}
</style>
</head>
<body>
<div class="img-box">
<img class="myimage" src="./resources/ocean.jpg" />
<div class="del-icon"></div>
</div>
</body>
</html>
