定義dom，容器中包含文本，並且包含4個 用於特效， 的data-text 屬性值為與文字相同：
<p> web <span></span> <span></span> <span></span> <span></span> </p>
居中顯示：
html, body {
height: 100%;
display: flex;
align-items: center;
justify-content: center;
background: black;
}定義文字樣式：
.rainbow {
color: white;
font-size: 300px;
text-transform: uppercase;
font-family: sans-serif;
font-weight: bold;
line-height: 1em;
position: relative;
}用偽元素增加圖層，形成彩虹效果：
.rainbow span::before,
.rainbow span::after {
content: attr(data-text);
position: absolute;
top: 0;
left: 0;
overflow: hidden;
}
.rainbow span:nth-child(1)::before {
color: orchid;
z-index: 1;
height: calc(100% - 10% * 1);
}
.rainbow span:nth-child(1)::after {
color: mediumpurple;
z-index: 2;
height: calc(100% - 10% * 2);
}
.rainbow span:nth-child(2)::before {
color: deepskyblue;
z-index: 3;
height: calc(100% - 10% * 3);
}
.rainbow span:nth-child(2)::after {
color: cyan;
z-index: 4;
height: calc(100% - 10% * 4);
}
.rainbow span:nth-child(3)::before {
color: mediumspringgreen;
z-index: 5;
height: calc(100% - 10% * 5);
}
.rainbow span:nth-child(3)::after {
color: yellow;
z-index: 6;
height: calc(100% - 10% * 6);
}
.rainbow span:nth-child(4)::before {
color: gold;
z-index: 7;
height: calc(100% - 10% * 7);
}
.rainbow span:nth-child(4)::after {
color: tomato;
z-index: 8;
height: calc(100% - 10% * 8);
}增加動畫效果：
.rainbow span::before,
.rainbow span::after {
animation: animate 0.8s infinite alternate;
filter: opacity(0);
}
@keyframes animate {
from {
filter: opacity(0);
}
to {
filter: opacity(1);
}
}為圖層設定延時，增強動感：
.rainbow span:nth-child(1)::before {
animation-delay: calc(0.8s - 0.1s * 1);
}
.rainbow span:nth-child(1)::after {
animation-delay: calc(0.8s - 0.1s * 2);
}
.rainbow span:nth-child(2)::before {
animation-delay: calc(0.8s - 0.1s * 3);
}
.rainbow span:nth-child(2)::after {
animation-delay: calc(0.8s - 0.1s * 4);
}
.rainbow span:nth-child(3)::before {
animation-delay: calc(0.8s - 0.1s * 5);
}
.rainbow span:nth-child(3)::after {
animation-delay: calc(0.8s - 0.1s * 6);
}
.rainbow span:nth-child(4)::before {
animation-delay: calc(0.8s - 0.1s * 7);
}
.rainbow span:nth-child(4)::after {
animation-delay: calc(0.8s - 0.1s * 8);
}最後，把原始文字設定為透明色：
.rainbow {
color: transparent;
}大功告成！
