Causes of CSS code compression, why CSS compression is needed
CSS code compression is the best The main factor is that the number of bytes occupied by the compressed CSS code is reduced (the file size is reduced). If the website has a relatively small number of visits, the advantage of the compressed code is not very obvious. But for relatively large websites, it is necessary to save money on websites with large traffic. On the one hand, it can save traffic; on the other hand, it can make the website open slightly faster (visitors may not feel this speed, but it is true) exists), especially some website spaces are now paid based on monthly traffic usage or the monthly traffic usage is limited after purchasing the space. If compressed, the traffic usage will be greatly reduced, thereby saving costs.

For example, the CSS will be placed on a third-party server and the website will use LINK to link to the external CSS file. The CSS file will be placed on a third-party paid OSS (development storage space, such as Alibaba). Cloud storage) are charged based on traffic. Compression of CSS code will naturally reduce traffic consumption due to large visits and thus lower costs.
