文字閃爍特效 html+css

上效果先:
先言:
看過我文章可以知道,這東西似曾相識~ ╭(●`∀´●)╯確實,這個和我另一篇文章“文字點閃特效”原理是差不多的
實現:
1.定義html標籤:
<h1>
<span>佛</span>
<span>主</span>
<span>保</span>
<span>佑</span>
<span>,</span>
< span>考</span>
<span>試</span>
<span>全</span>
<span>過</span>
<span>!</span>
</h1>
2.文字的基本樣式,大小顏色等:
h1{
font-family: 'fangsong';
font-size: 6em;
color: transparent;
}
span{
display: table-cell;
animation: san 3s linear infinite;
}
display: table-cell;此元素會作為一個表格單元格顯示(類似 和 )
color: transparent;文字顏色透明
3.文字發亮的效果,就閃一下然後就又會(20%-80%的時候)變透明:
@keyframes san{
0%,100%{
color: rgb(255, 255, 255);
text-shadow : 0 0 5px rgb(1, 231, 247),
0 0 15px rgb(1, 231, 247),
0 0 25px rgb(1, 231, 247),
0 0 50px rgb(1, 231, 247),
0 0 80px rgb(1, 231, 247),
0 0 120px rgb(1, 231, 247),
0 0 160px rgb(1, 231, 247),
0 0 200px rgb(1, 231, 247),
0 0 300px rgb(1, 231, 247),
0 0 400px rgb(1, 231, 247),
0 0 500px rgb(1, 231, 247);
}
20%,80%{
color: transparent;
text-shadow: none;
}
}
text-shadow:是給它加陰影,寫了很多行是為了陰影更亮;
4.製造時間差,讓不同的時間不同的文字亮;
h1 span:nth-child(1){
animation-delay:0s;
}
h1 span:nth-child(2){
animation-delay:0.1s;
}
h1 span:nth-child(3){
animation-delay:0.2s;
}
h1 span:nth-child(4){
animation-delay:0.3s;
}
h1 span:nth-child(5){
animation-delay:0.4s;
}
h1 span:nth-child(6){
animation-delay:0.5s;
}
h1 span:nth-child(7){
animation-delay:0.6s;
}
h1 span:nth-child(8){
animation-delay:0.7s;
}
h1 span:nth-child(9){
animation-delay:0.8s;
}
h1 span:nth-child(10){
animation-delay:0.9s;
}
animation-delay 等待多少秒,然後才開始動畫;
