定义 DOM,容器中包含 2 段文本:
<div class="container">
<p>Explorer</p>
<p>Discovery</p>
</div>
居中显示:
body {
margin: 0;
height: 100vh;
display: flex;
align-items: center;
justify-content: center;
background-color: black;
}
设置字体样式:
p {
color: white;
font-size: 100px;
font-weight: bold;
font-family: sans-serif;
text-transform: uppercase;
text-align: center;
}
让 2 段文本重叠:
p {
margin: 0;
}
p:nth-child(1) {
transform: translateY(50%);
}
p:nth-child(2) {
transform: translateY(-50%);
}
定义动画,让 2 段文本交替显示:
p {
animation: show-hide 10s infinite;
filter: opacity(0);
}
p:nth-child(1) {
animation-direction: normal;
}
p:nth-child(2) {
animation-direction: reverse;
}
@keyframes show-hide {
0% {
filter: opacity(0);
}
25% {
filter: opacity(1);
}
40% {
filter: opacity(1);
}
50% {
filter: opacity(0);
}
}
增加字间距的变化效果:
@keyframes show-hide {
0% {
filter: opacity(0);
letter-spacing: -0.8em;
}
25% {
filter: opacity(1);
}
40% {
filter: opacity(1);
}
50% {
filter: opacity(0);
letter-spacing: 0.24em;
}
}
增加文本模糊效果:
@keyframes show-hide {
0% {
filter: opacity(0) blur(0.08em);
letter-spacing: -0.8em;
}
25% {
filter: opacity(1) blur(0.08em);
}
40% {
filter: opacity(1) blur(0.24em);
}
50% {
filter: opacity(0) blur(0.24em);
letter-spacing: 0.24em;
}
}
最后,为容器设置对比度滤镜:
.container {
filter: contrast(10);
background-color: black;
overflow: hidden;
}
大功告成!
