Why?

Answer 1

1) a property without a prefix is ​​written at the end so that when browsers start supporting it, it will override those with a prefix.

-webkit-animation: dinamic 1s infinite steps(4);
-moz-animation: dinamic 1s infinite steps(4);
animation: dinamic 1s infinite steps(4);

2) the last version of the mozilla browser that supported -moz-animation was released in 2012. no one uses it anymore. Mozilla has long supported animation without a prefix.
