CSS3-转换延迟仅在关闭时？

Question

a {
background: white;    
transition: background 1s ease;
transition-delay: 1s;
}

b {
background: black;
}

This makes the transition close after 1s, but also start. Would it be possible to make it open immediately but close after 1s?

Answer 1

Use the following code instead of yours. Let me know :

a {
  background: white;    
  transition: background 1s ease;
  transition-delay: 0s;
  transition-duration:5s;
  }

b {
 background: black;
 }
