1.通过改变透明度来实现文字的渐变闪烁，效果图：
<!DOCTYPE html>
<html>
<head>
</head>
<title>文字闪烁</title>
<body>
<div class="blink">
星星之火可以燎原
</div>
</body>
<style>
.myclass{
letter-spacing:5px;/*字间距*/
color: red;
font-weight:bold;
font-size:46px;
}
/* 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: red;
font-size:46px;
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>
</html>
<!DOCTYPE html>
