this is the carousel graph code I copied directly from the official website of element. The parity is in effect, so the attribute should be used correctly, right? However, the 
 number is not valid. 
 
 
 this kind of thing also happened when I was learning this attribute. The numbers always don"t work. I don"t know if I don"t understand it or I don"t know what the problem is. No, no, no.
