我正在使用相对和绝对位置，但它不起作用。 我错在哪里？
我的HTML代码:
null
.slide-item {
text-align: center;
height: 400px;
position: relative;
}
.slide-item img {
display: block;
}
.slide-item .sale {
position: absolute;
top: -20px;
right: 20px;
display: block;
}<div class="slide-item">
<div class="sale">
<img src="https://via.placeholder.com/50" alt="">
</div>
<img src="https://via.placeholder.com/150" class="arr-img" alt="">
</div>null
请尝试此代码。。。
<!DOCTYPE html>
<html>
<head>
<style>
.slide-item {
text-align: center;
height: 400px;
position: relative;
}
.slide-item img:nth-child(2){
position: relative;
width: 1150px;
height: 600px;
left: 65px;
top: 25px;
}
.slide-item img {
display: block;
}
.slide-item .sale img {
position: absolute;
top: 0px;
right: 150px;
z-index: 1;
}
</style>
</head>
<body>
<div class="slide-item">
<div class="sale">
<img src="img/icons8-round-128.png" alt="">
</div>
<img src="img/111713927-green-screen-green-background-green-screen-stock-footage-video.jpg" class="arr-img" alt="">
</div>
</body>
