}
(3)html file body part
1. Quick use
Add the following attributes to the initial p:hover
Transition: background 2s linear 1s,height 1s linear 1s;
2. Detailed explanation
(1)Specify separately and explain the attributes in detail
Add the following attributes to the initial p:hover
transition-property:height,background-color;
transition-duration:1s,2s;

transition-duration height takes 1s from execution to end, and background-color takes 2s from execution to end. After the height change ends, there is still 1s left after the background-color change ends
If you only write one value, this value will be applied to all attributes. In addition, please make the number of transition-duration values equal to the number of transition-duration values
transition-timing-function: linear; Please find the changing rules here
If you only write one value, this value will be applied to all properties. In addition, please make the number of transition-timing-function values equal to the number of transition-property values
transition-delay: 1000ms, 1s; height starts to change after 1s, here background-color and height start to change at the same time
If you only write one value, this value will be applied to all properties. In addition, please make the number of transition-delay values equal to the number of transition-property values
