保姆级运行教学

如果有非计算机专业的同学不知道怎么运行代码,请接着往下看:

首先,在电脑桌面右击新建一个文本文档,并将上面给的代码复制粘贴进去,保存。

然后重命名这个文本文档,把后缀.txt改为.html格式


点击“是”即可,这时候这个文件就变成你浏览器的图标了,双击即可打开(也可以发给你喜欢的人,他可以直接在电脑上打开)

如果文件没有变成浏览器图标的话,右击这个文件,选择打开方式用你的浏览器打开即可。

效果实现啦:

补充:部分朋友反应的修改了文件扩展名后没有弹出是否更改的选项,应该是你的电脑没有开启文件扩展名选项,大家打开“此电脑”后,点击查看——显示——勾选文件扩展名,然后再去修改即可!


添加背景图片

在上面代码的第17行“position: absolute;”后添加下面这两行代码

         background-image: url("love.jpg");
         background-size: contain;

然后在桌面把你想添加的背景图片命名为love.jpg即可!

实现效果:
