/* 1.定义基础样式 一般图片使用一倍图jpg，使用tying进行压缩,图标使用二部图的png*/
/* 2.尽量使用标准流,其余则有规律的容器使用flex,无规律使用定位 */
/* 3.使用img构图,非必要不使用背景图 */
/* 4.标题当pc与mobile换行一致时可使用br标签,否则在pc端固定h4标题的宽度用于换行 */
/* 5.图片--pc端使用固定宽高,mobile端使用vw进行自适应 */
/* 6.一般position为absolute的元素使用vw自适应 */
/* 7.使用vw自适应时,一般使用vw,不使用vh,因为vh在部分手机上会出现滚动条 */
/* 8.mobile端中的动画--图片，必须处于正方形的div中，且整个动画内容尽量保持 3/2 的高宽比,留出空隙用于顶底部的交互 */
