How can I prevent jank and reduce layout shift with responsive sized images?

由 北慕城南 提交于 2021-02-20 10:15:33

Since my images are responsive, I can't specify exact sizes of the images, or have placeholders to reserve the space. What is a modern way to prevent CLS with responsive images?

Could some one point me in the right
