前言
我是前端小刘不怕牛牛,<font color=skyblue>love you 3000</font>,愿你能遇到值得的人。今天分享一个唯美的文字闪烁 CSS 特效希望大家能喜欢
效果图
HTML 篇
代码:
<div class="main">
<div>
<span>I</span></div>
<div>
<span>l</span>
<span>o</span>
<span>v</span>
<span>e</span></div>
<div>
<span>y</span>
<span>o</span>
<span>u</span></div>
<div>
<span>3</span>
<span>0</span>
<span>0</span>
<span>0</span></div>
</div>
这里将每个字母分别用盒子包住是为了后面设置动画延迟,保证文字闪烁呈现流水型
还记得 span 是行内元素吧,它们可以在同一行排列,不过 div 不能,所以我们还需要用
display
转换 div 的元素显示模式为inline-block
这里可能小伙伴会有疑问为什么还要用 div 将每个单词保住,这里是因为后面用 flex 布局,让单词之间自动设置间隙,整体更加好看
CSS 篇
1. 盒子模型设置
代码如下:
body{
background-color: black;
}
.main{
padding-top: 249px;
margin: 0 auto;
width: 1200px;
display: flex;
justify-content: space-around;
font-family: 'Courier New', Courier, monospace;
}
.main div{
display: inline-block;
color: transparent;
}
span{
font-size: 120px;
animation: twinkle 4.6s linear infinite;
}
这里用到 flex 布局的
justify-content
属性,display 为 flex 的父元素的子元素称为项目,而space-around
属性值,则使项目之间根据父元素宽度平均分布间隔,(两端与项目之间也会分配间隔,为项目与项目之间间隔的一半,这个在案例中不重要)这里对 span 标签选择,设置动画,
animation
属性可以连写第一个值
twinkle
为动画名字第二个为
duration
,动画播放时长第三个值为
timing-function
,时间过渡曲线,linear 为线性过渡,动画播放无倍数变换第四个值为播放次数,infinity 为无限循环
将文字颜色设置为透明,当然也可以用
opacity
2. 动画设置
代码如下:
.main div:nth-child(1) span:nth-child(1){
animation-delay: 0s;
}
.main div:nth-child(2) span:nth-child(1){
animation-delay: 0.4s;
}
.main div:nth-child(2) span:nth-child(2){
animation-delay: 0.8s;
}
.main div:nth-child(2) span:nth-child(3){
animation-delay: 1.2s;
}
.main div:nth-child(2) span:nth-child(4){
animation-delay: 1.6s;
}
.main div:nth-child(3) span:nth-child(1){
animation-delay: 2.0s;
}
.main div:nth-child(3) span:nth-child(2){
animation-delay: 2.4s;
}
.main div:nth-child(3) span:nth-child(3){
animation-delay: 2.8s;
}
.main div:nth-child(4) span:nth-child(1){
animation-delay: 3.2s;
}
.main div:nth-child(4) span:nth-child(2){
animation-delay: 3.6s;
}
.main div:nth-child(4) span:nth-child(3){
animation-delay: 4s;
}
.main div:nth-child(4) span:nth-child(4){
animation-delay: 4.4s;
}
@keyframes twinkle{
0%{
color: transparent;
}
100%{
color: aliceblue;
text-shadow: 0 0 4px skyblue,
0 0 10px skyblue,
0 0 20px skyblue,
0 0 30px skyblue,
0 0 40px skyblue,
0 0 50px skyblue,
0 0 60px skyblue,
0 0 70px skyblue,
0 0 80px skyblue,
0 0 90px skyblue,
0 0 100px skyblue,
0 0 110px skyblue,
0 0 120px skyblue,
0 0 130px skyblue;
/* 文字阴影叠加 */
}
}
给每个 span 盒子设置各自的动画延迟时间,实现流水型效果
这里需要注意复合选择器写法和 nth-child 方法的选择方式
创建动画播放,上面用文字阴影叠加效果,实现文字闪烁,其实一些好看的文字特效,阴影部分都是用叠加的效果做的,大家还可以试一下用多个颜色叠加,做出个五彩斑斓的黑如何?
(随便叠了一个)
