html中的响应式图片

  1. img

    sizes 指定屏幕尺寸
    
srcset 指定可以使用的图片和大小，多个使用逗号分隔，需要指定图片的真实宽度，个人觉得没有picture好用
    
<img
    
    sizes="(min-width: 1200px) 680px, (min-width: 640px) 500px, 300px"
    
    srcset="https://timgsa.baidu.com/timg?image&quality=80&size=b9999_10000&sec=1549557630523&di=2513b0fcc78a65820a90319ccff64abc&imgtype=0&src=http%3A%2F%2Fn.sinaimg.cn%2Fsports%2F2_img%2Fsipaphoto%2F49d350e9%2F20171027%2FJlH_-fynfvfi1121420.jpg 680w"
    
alt="">

  2. picture

    <picture>
    
    <source media="(min-width: 1200px)" srcset="https://timgsa.baidu.com/timg?image&quality=80&size=b9999_10000&sec=1549557630523&di=2513b0fcc78a65820a90319ccff64abc&imgtype=0&src=http%3A%2F%2Fn.sinaimg.cn%2Fsports%2F2_img%2Fsipaphoto%2F49d350e9%2F20171027%2FJlH_-fynfvfi1121420.jpg" />
