请问我的图片间距为什么不对呢？
<!DOCTYPE html>
<html>
<head>
<title>几米的书—网页</title>
<meta charset="utf-8">
<style type="text/css">
*{margin:0;padding:0px;}
.content{border:4px solid #badbdb; padding: 44px 15px 15px;width: 736px;}
.book{background:url(E:/CSStest/buju/case2/images/t_book.gif) no-repeat #eff9f9}//为什么显示不出照片呢
img{margin:10px 18px;border:1px solid #b1adad;}
</style>
</head>
<body>
<div class="content book">
<img src="E:\CSStest\buju\case2\images\book1.jpg" width="80px" height="80px">
<img src="E:\CSStest\buju\case2\images\book2.jpg" width="80px" height="80px">
<img src="E:\CSStest\buju\case2\images\book3.jpg" width="80px" height="80px">
<img src="E:\CSStest\buju\case2\images\book4.jpg" width="80px" height="80px">
<img src="E:\CSStest\buju\case2\images\book5.jpg" width="80px" height="80px">
<img src="E:\CSStest\buju\case2\images\book6.jpg" width="80px" height="80px">
</div>
</html>
</body>感觉img{margin:10px 18px;border:1px solid #b1adad;}这句根本没有起作用，边框没有，间距不对。。。结果如下图
