图片还是不能随屏幕的变化而变化?

同学你好,代码中的问题:
1、宽度条件要用()表示,不是{}哦:

2、不需要使用flex布局,使用媒体查询控制图片的宽度即可。
3、图片的选择器要使用之前的#box>img,否则只使用img是覆盖不了之前设置的样式的,选择器权重不够。
可以参考下面修改的:
<!DOCTYPE html>
<html>
<head>
<meta charset="UTF-8">
<title>Document</title>
<!-- <meta name=""> -->
<style>
#box {
width: 80%;
margin: 0 auto;
background: #ccc;
text-align: center;
}
#box>img {
display: inline-block;
padding: 1.5%;
width: 21%;
height: 200px;
}
/*此处写代码*/
/*
#box {
display: flex;
flex-wrap: wrap;
}*/
@media screen and (min-width:960px) {
#box>img {
width: 21%;
}
}
@media screen and (min-width:780px) and (max-width: 961px) {
#box>img {
width: 29%;
}
}
@media screen and (min-width:440px) and (max-width: 780px) {
#box>img {
width: 46%;
}
}
@media screen and (max-width: 440px) {
#box>img {
width: 100%;
}
}
</style>
