文字闪烁效果一：
通过改变透明度来实现文字的渐变闪烁，效果如下：
文字带渐变效果的闪烁：
<div class="main">
文字闪烁：<span class="blink">闪烁效果</span>
</div>
<style type="text/css">
.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;
}
</style>
如果不需要渐变闪烁效果，我们可以在keyframe动画中定义50%，50.1%的opacity的值。如下：
@-webkit-keyframes blink {
0% { opacity: 1; }
50% { opacity: 1; }
50.01% { opacity: 0; }
100% { opacity: 0; }
}
这样的效果：
文字不渐变闪烁：闪烁效果
文字闪烁效果二：
通过设置text-shadow的值，来实现文字阴影闪烁的效果，效果如下：
闪烁效果
代码如下：
<div class="box">闪烁效果</div>
<style>
.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}
}
</style>
文字闪烁效果三：
利用背景图片或者背景渐变，实现文字颜色的闪烁效果，效果如下：

代码如下：
<span class="box">闪烁效果</span>
<style>
.box{
display: inline-block;
font-size: 20px;
margin: 10px;
background: linear-gradient(left, #f71605, #e0f513);
background: -webkit-linear-gradient(left, #f71605, #e0f513);
background: -o-linear-gradient(right, #f71605, #e0f513);
-webkit-background-clip: text;
-webkit-text-fill-color: transparent;
animation:scratchy 0.253s linear forwards infinite;
/* 其它浏览器兼容性前缀 */
-webkit-animation:scratchy 0.253s linear forwards infinite;
-moz-animation: scratchy 0.253s linear forwards infinite;
-ms-animation: scratchy 0.253s linear forwards infinite;
-o-animation: scratchy 0.253s linear forwards infinite;
}
