本篇文章主要介绍了如何实现css图片自适应屏幕的效果。对于新手来说最简单的方法，即图片写在div里面的背景里。这样就能自适应屏幕大小且不会出现横向的滚动条。

css图片自适应屏幕代码示例如下：

background:url(1.jpg) center no-repeat;
background:url(图片地址) 0 0 no-repeat scroll transparent;background-size:100% 100%;
/* 图片固定在ims里面*/
<div class="ims">
<img src="/static/imghwm/default1.png"  data-src="1.jpg"  class="lazy"    style="max-width:90%"  alt="">
</div>

注：在html里面插入图片，如果想让图片自适应屏幕的小而不是宽高固定不变可以在css代码里加入

img { height: auto; width: auto\9; width:100%; }

\9是hack css 的一种写法，这种在正常css代码后面加"\9"的方式，只有IE浏览器才能识别，其他浏览器会忽略这条语句。这样就能做到差异化浏览器，来达到兼容浏览器的目的。
