    三、项目结构

    四、总结
    4.1、“height:98vh;”中vh表示浏览器的高度,98vh表示98%的浏览器高度,vw表示浏览器的宽度
    4.2、@media screen and (max-width: 1600px) { },这个表示响应式布局 - 屏幕尺寸宽度小于1600px 时,会发生的布局变化,同理@media screen and (max-height: 1600px) { }表示响应式布局 - 屏幕尺寸高度小于1600px 时,会发生的布局变化
    4.3、要显示圆形图片,只需要在图片上加“border-radius:50%;”属性
    4.4、背景透明:BACKGROUND-COLOR: transparent;
    4.5、字体设置:font-family: "Microsoft YaHei";微软雅体;font-style:normal;字体风格;font-weight:normal;字体粗细;font-size:20px;字体大小
