CSS background wizard technology is a web page picture application processing method. It allows you to put all the sporadic pictures involved in a page into a large picture, and then use the combination of "background-image", "background- repeat" and "background-position" of CSS to locate the background, and background-position can accurately locate the background picture with numbers. In this way, when you visit the page, the loaded images will not be displayed as slowly as before.

Advantages:

1. It can reduce the http requests of the web page, thus greatly improve the performance of the page, which is also the biggest advantage of CSS Sprites, and also the main reason why it is widely spread and used.

2.CSS Sprites can reduce the bytes of pictures. It has been compared many times that the bytes of 3 pictures merged into one picture are always less than the sum of the bytes of these three pictures.

3. To solve the problem of web designers in picture naming, we only need to name a collection of pictures, and there is no need to name every small element, so as to improve the efficiency of web page production.

4. It is convenient to change the style, only need to change the color or style of the picture on one or fewer pictures, and the style of the whole page can be changed. It is more convenient to maintain.

Disadvantages:

1. When merging pictures, you should merge multiple pictures into a single picture in an orderly and reasonable manner, and leave enough space to prevent unnecessary backgrounds in the plate; fortunately, the most painful thing is in the wide screen, the adaptive page under the high-resolution screen, if your picture is not wide enough, it is easy to break the background.

2.CSS Sprites is more troublesome in maintenance, if the background of the page has a little change, it is generally necessary to change the merged picture, the place that does not need to change had better not to move, so as to avoid changing more css, if you can't put it in the original place, you can only (preferably) add pictures down, so the bytes of the picture will increase, and you should also change the css.
