HTML5文字特效代碼是一種可以讓網(wǎng)頁文本更生動(dòng)、更具有吸引力的技術(shù)。下面是一些常用的HTML5文字特效代碼：

<style>
/* 豎直折疊特效 */
.fold {
position: relative;
overflow: hidden;
}
.fold::before,
.fold::after {
content: "";
position: absolute;
width: 100%;
height: 50%;
left: 0;
background-color: #333;
transform-origin: top;
transition: transform .5s;
}
.fold::before {
top: 0;
transform: scaleY(0);
}
.fold::after {
bottom: 0;
transform: scaleY(1);
}
.fold:hover::before {
transform: scaleY(1);
}
.fold:hover::after {
transform: scaleY(0);
}
/* 斜角滑動(dòng)特效 */
.slide {
display: inline-block;
position: relative;
z-index: 1;
overflow: hidden;
padding-top: .25em;
}
.slide::before,
.slide::after {
content: "";
position: absolute;
z-index: -1;
top: 0;
bottom: 0;
left: 0;
right: 0;
background-color: #333;
transform: skewX(-30deg) translateX(-100%);
transition: transform .5s;
}
.slide::after {
transform: skewX(30deg) translateX(-100%);
}
.slide:hover::before {
transform: skewX(-30deg) translateX(100%);
}
.slide:hover::after {
transform: skewX(30deg) translateX(100%);
}
/* 漸變特效 */
.gradient {
background: linear-gradient(to right, #fff, #f00, #00f, #fff);
background-size: 200% 200%;
background-position: 0 50%;
text-shadow: 0 0 10px rgba(255, 255, 255, .5);
-webkit-animation: gradient 10s ease infinite;
animation: gradient 10s ease infinite;
}
@-webkit-keyframes gradient {
0% {
background-position: 0 50%;
}
50% {
background-position: 100% 50%;
}
100% {
background-position: 0 50%;
}
}
@keyframes gradient {
0% {
background-position: 0 50%;
}
50% {
background-position: 100% 50%;
}
100% {
background-position: 0 50%;
}
}
</style>
<p class="fold">折疊特效文字</p>
<p class="slide">斜角滑動(dòng)特效文字</p>
<p class="gradient">漸變特效文字</p>

以上代碼分別實(shí)現(xiàn)了豎直折疊、斜角滑動(dòng)和漸變?nèi)N文字特效。這些代碼可以讓網(wǎng)頁文本更加生動(dòng)有趣，從而吸引用戶的注意力。
