1、打开html开发软件,新建一个html代码页面。

2、在html代码页面的标签里面输入多行段落文字,用于后面浏览器滚动条滚动的时候查看图片时候随滚动条而滚动条。

3、设置背景图片样式。在标签后面创建一个<style>标签,然后在这个标签里设置<body>标签的背景图片,以及背景图片不重复。</p> <p><img loading="lazy" class="ikqb_img"

<p>第3,你的路径不要写错,在谷歌或者其他浏览器当中,点击F12键,调出控制台,查看是否有错误,如果有文件没有加载成功,则说明你的相应文件没有成功引入</p> <p>第4,body当中需要有内容,默认body的高度是由内容撑开的,没有内容body就没有高度,背景图自然无法看到<br></p> <p>最后,建议你弄本书系统的学一学,里面包括一些类名的命名,书写的规范,在你代码当中都有不少不合适的地方,毕竟学东西是为了有实际的用处,既然要写代码,写的规范一些,按照开发行业标准来写岂不是更好。HTML与CSS方面,推荐《HTML5布局之路》,JS,可以借助《Head First JavaScript程序设计》来入门</p></p> </div> </div> <div
