文字闪烁效果1：

通过改变透明度，文字逐渐闪烁。 效果如下：

文字闪烁渐变效果：

.main{
  color: #666;margin-top: 50px;
}
/* 定义keyframe动画，命名为blink */
@keyframes blink{
  0%{opacity: 1;}
  100%{opacity: 0;} 
}
/* 添加兼容性前缀 */
@-webkit-keyframes blink {
    0% { opacity: 1; }
    100% { opacity: 0; }
}
@-moz-keyframes blink {
    0% { opacity: 1; }
    100% { opacity: 0; }
}
@-ms-keyframes blink {
    0% {opacity: 1; } 
    100% { opacity: 0;}
}
@-o-keyframes blink {
    0% { opacity: 1; }
    100% { opacity: 0; }
}
/* 定义blink类*/
.blink{
    color: #dd4814;
    animation: blink 1s linear infinite;  
    /* 其它浏览器兼容性前缀 */
    -webkit-animation: blink 1s linear infinite;
    -moz-animation: blink 1s linear infinite;
    -ms-animation: blink 1s linear infinite;
    -o-animation: blink 1s linear infinite;
}

如果不需要渐变闪烁效果css3闪入，我们可以在关键帧动画中定义不透明度值50%和50.1%。 如下：

@-webkit-keyframes blink {
    0% { opacity: 1; }
    50% { opacity: 1; }
    50.01% { opacity: 0; }
    100% { opacity: 0; }
}

这样的治疗效果：

文字闪烁效果二：

通过设置text-shadow的值css3闪入，实现文字阴影闪烁的效果。 效果如下：

    .box{ 
    	font-size: 20px; 
    	color:#4cc134; 
    	margin: 10px;
    	animation: changeshadow 1s  ease-in  infinite ;
    	/* 其它浏览器兼容性前缀 */
	    -webkit-animation: changeshadow 1s linear infinite;
	    -moz-animation: changeshadow 1s linear infinite;
	    -ms-animation: changeshadow 1s linear infinite;
	    -o-animation: changeshadow 1s linear infinite;
    }  
    @keyframes changeshadow {  
        0%{ text-shadow: 0 0 4px #4cc134}  
        50%{ text-shadow: 0 0 40px #4cc134}  
        100%{ text-shadow: 0 0 4px #4cc134}  
    }
    /* 添加兼容性前缀 */
	@-webkit-keyframes changeshadow {
	  0%{ text-shadow: 0 0 4px #4cc134}  
          50%{ text-shadow: 0 0 40px #4cc134}  
          100%{ text-shadow: 0 0 4px #4cc134}  
	}
	@-moz-keyframes changeshadow {
	    0%{ text-shadow: 0 0 4px #4cc134}  
            50%{ text-shadow: 0 0 40px #4cc134}  
            100%{ text-shadow: 0 0 4px #4cc134}  
	}
	@-ms-keyframes changeshadow {
	    0%{ text-shadow: 0 0 4px #4cc134}  
            50%{ text-shadow: 0 0 40px #4cc134}  
            100%{ text-shadow: 0 0 4px #4cc134}  
	}
	@-o-keyframes changeshadow {
	    0%{ text-shadow: 0 0 4px #4cc134}  
            50%{ text-shadow: 0 0 40px #4cc134}  
            100%{ text-shadow: 0 0 4px #4cc134}  
	}
 

文字闪烁效果三：

使用背景图片或背景渐变来实现文字颜色闪烁的效果。 效果如下：
