CSS综合案例4

1. 综合案例

我们来做一个静态的轮播图。

2. 分析思路

首先需要加载一张背景图进去
需要4个小圆点，设置样式，并用定位和平移调整位置
添加两个箭头，也是需要用定位和位移进行调整位置

3. 代码演示

html文件

<!DOCTYPE html>
<html lang="en">
	<head>
		<meta charset="UTF-8" />
		<meta name="viewport" content="width=device-width, initial-scale=1.0" />
		<title>静态轮播图</title>
		<link rel="stylesheet" href="./style.css" />
	</head>
	<body>
		<div class="box">
			<img src="./R-C.jpg" alt="穿越火线" />
			<div class="arrow1">
				<p><</p>
			</div>
			<div class="arrow2">
				<p>></p>
