The two concepts of progressive enhancement and graceful demotion are fire after the advent of CSS3. Because the low-level browser does not support CSS3, but the CSS3 effect is too good to give up, so in the advanced browser to use CSS3, and in the low-level browser Only the most basic functions are guaranteed. The goal of both is to focus on different experiences under different browsers, but they are different in focus, leading to different workfl

I realized today that there are two ways to save JPEG files they are baseline JPEG (standard type) and progressive JPEG (progressive). Both formats have the same size and image data, and their extensions are the same, and the only difference is that they are displayed in a different way. Baseline JPEG This type of JPEG file is stored in a JPEG file in the order of each row, by scanning from top to bottom.

Before looking at some CSS3 effect demo, found that some write CSS3 properties, the compatibility of the order is not the same, such as transition properties, some put transition in front of some are put in the back, Of course, this may also include coder personal habits or compulsive > ". transition{ -webkit-transition:all. 5s; -moz-transition:all. 5s; -o-transition:all. 5s; Transition:all. 5s; }. transition{ Transition:all. 5s;　　 -o-transition:all. 5s; -moz-transitio

I. Introduction JPEG, GIF, and PNG image formats all provide a function to enable faster image display. Images can be stored in a special way. the sketch of the image is displayed first, and the details are filled after all files are downloaded (Baidu image, QQ space, this method is used when the big image is displayed ). This has a very meaningful psychological effect, because it makes people have something to watch, rather than sitting and waiting for large images to slowly display on the scre

Interlaced scanningEach frame is divided into two fields, each containing a frame of all the odd scan lines or even scan lines, usually first scan odd lines to get the first field, and then scan even rows to get the second field. Whether progressive or interlaced, there are three concepts for video files, transmission, and imaging, and these three concepts are interlinked but not identical. The first appearance is interlaced scanning, and the matching

There are two ways to save the JPEG file format. They are baseline JPEG and progressive JPEG. Both formats have the same size and image data, and their extensions are the same, and the only difference is the way they are displayed.

Recently reading a Web experience related to the book "Progressive Enhancement-cross-platform user experience Design", read to do some summary, digest the essence of the book.Before reading this article, you can think about the following questions first.1. What is the purpose of browsing the Web?2. What problems will you encounter when browsing the Web?3. What are the ways to solve these problems?4. What are the specific implementation steps of these
