								CSS动画为网页增添了美感。 CSS动画可以将CSS样式转换为另一种CSS样式。

								要创建CSS动画序列,我们在CSS的`animation`属性中有不同的子属性:

							| 
								
							 | 
							
								
							 | 
							
								
							 | 
							
								
									
								 |

								*   `animation-delay`
							 | 
						
					
						
							| 
								
							 | 
							
								
							 | 
							
								
							 | 
							
								
									
								 | 
							
							
								*   `animation-direction`
							 |

							 | 
							
								
							 | 
							
								
							 | 
							
								
									
								 | 
							
							
								*   `animation-duration`
							 | 
						
					
						
							| 
								
							 | 
							
								
							 | 
							
								
							 | 
							
								
									
								 | 
							
							
								*   `animation-iteration-count`
							 | 
						
					
						
							| 
								
							 | 
							
								
							 | 
							
								
							 | 
							
								
									
								 | 
							
							
								*   `animation-name`
							 | 
						
					
						
							| 
								
							 | 
							
								
							 | 
							
								
							 | 
							
								
									
								 | 
							
							
								*   `animation-play-state`
							 | 
						
					
						
							| 
								
							 | 
							
								
							 | 
							
								
							 | 
							
								
									
								 | 
							
							
								*   `animation-timing-function`
							 | 
						
					
						
							| 
								
							 | 
							
								
							 | 
							
								
							 | 
							
								
									
								 | 
							
							
								*   `animation-fill-mode`
							 | 
						
					
						
							| 
								
							 |
