A friend showed me a carousel effect. I downloaded the js and took a look. Such a simple effect of Yaya can be written in hundreds of lines. It seriously affects the loading speed of the browser. I thought that people have broadband Traffic is free to play. . In desperation, I wrote a simple one for him. All the codes did not exceed 70 lines, and there was also the CSS with rounded corners. Not every browser has rounded corners, but it does not affect the appearance, hehe.
