wide in the viewport, the picture we prepare for the big screen can be displayed, but if we can use more vertical space, the effect will be better.

In the wide view of the phone screen, our pictures, the pictures for the big screen, can be displayed, but if you can make more use of vertical space, the effect will be better. This can be seen through the screenshot below: A good response-style picture technology should allow us to provide appropriate images for small screens, to meet small files, fast loading, and to improve design requirements.

technique that uses a script to generate a picture. Usually this technique is used to achieve the resolution adaptation of the picture. One example is Picturefill. When you think of "preload" and "response picture"--preload will load the src of the picture in advance, but the response-style picture technology usually has no SRC, or just has a 1x1 alternative picture. There is a conflict between the two technologies. Here are some trade-offs: D

Imagine the current browser script download will block other resources, face the page so large number of scripts, page performance will be bad to what extent.Preloaded and responsive picturesThen we go back to Jason Grigsby's tweet: I have to admit a little. I'm trying to push the responsive picture, and I'm increasingly inclined to encourage developers to use JS to block preloading. Jaso

device. In this way, on small-sized devices, or on large-sized devices, the device can independently take the dominant image to load different image clipping versions. If you want to provide image versions of different resolutions for a higher-density display, you can add additional file names in the srcset attribute. For example, let's take a look at the Retina code processing segment with a pixel density of 2x: Current usage of Elements Now, Chrome,

gracefully downgrade images from WebP to other widely supported image formats, such as Jpeg: type="image/webp" srcset="image-l.webp" media="(min-width: 640px)"> type="image/webp" srcset="image-m.webp" media="(min-width: 320px)"> type="image/webp" srcset="image-s.webp"> srcset="image-l.jpg" media="(min-width: 640px)"> srcset="image-m.jpg" media="(min-width: 320px)"> srcset="image-s.jpg"> alt="Description of the image" src="image-l.jpg">We use Scott Jehl

have to make a basic distinction for screens of different pixel densities. Read this article about Srcset, or use tools such as Picturefill to ensure cross-browser support. If you feel the whole package is overwhelmed, start with the small part. Gradually adjust the Srcset property of the picture element is a good start, in the process, you will gradually see the response of the page more and more reliable. 　4, starting from the basic elements of th
