HTML+CSS 波浪式模糊文字特效

效果演示

实现了一个文字模糊消失的效果，包括一个容器（.container）和一个标题（h2）。标题中的文字由多个span元素组成，通过鼠标悬停实现逐个消失的效果。整个容器背景颜色为黑色，使文字效果更加突出。

CSS

* {
    margin: 0;
    padding: 0;
}

.container {
    height: 100vh;
    display: flex;
    justify-content: center;
    align-items: center;
    overflow: hidden;
    background-color: #212121;
}

h2 {
    display: flex;
    font-size: 160px;
    color: #fff;
    text-align: center;
    text-transform: uppercase;
    cursor: pointer

h2 span {
    transition: 1.5s;
}

h2:hover span {
    filter: blur(20px);
    opacity: 0;
    transform: scale(2);
}

h2 span:nth-child(1) {
    transition-delay: 0.1s;
}

h2 span:nth-child(2) {

h2 span:nth-child(8) {

实现思路拆分

* {
    margin: 0;
    padding: 0;
}

这段代码是设置所有元素的外边距和内边距为0。

.container {
    height: 100vh;
    display: flex;
    justify-content: center;
    align-items: center;
    overflow: hidden;
    background-color: #000;
}

这段代码是设置容器的高度为100vh，使用flex布局，使其水平和垂直居中。同时设置overflow为hidden，使其超出部分隐藏。并且设置背景颜色为黑色。

h2 {
    display: flex;
    font-size: 160px;
    color: #fff;
    text-align: center;
    text-transform: uppercase;
    cursor: pointer
}

这段代码是设置标题的布局方式为flex，并且使其水平和垂直居中。同时设置字体大小为160px，颜色为白色，文本对齐方式为居中，文本转换为大写，鼠标指针为手型。

h2 span {
    transition: 1.5s;
}

这段代码是设置标题中每个字母的过渡效果为1.5s。

h2:hover span {
    filter: blur(20px);
    opacity: 0;
    transform: scale(2);
}

这段代码是设置当鼠标悬停在标题上时，标题中每个字母的模糊程度为20px，透明度为0，缩放为原来的2倍。

h2 span:nth-child(1) {
    transition-delay: 0.1s;
}

h2 span:nth-child(2) {
    transition-delay: 0.2s;
}

h2 span:nth-child(3) {
    transition-delay: 0.3s;
}

h2 span:nth-child(4) {
    transition-delay: 0.4s;
}

h2 span:nth-child(5) {
    transition-delay: 0.5s;
}

h2 span:nth-child(6) {
    transition-delay: 0.6s;
}

h2 span:nth-child(7) {
    transition-delay: 0.7s;
}

h2 span:nth-child(8) {
    transition-delay: 0.8s;
}

h2 span:nth-child(9) {
    transition-delay: 0.9s;
}

h2 span:nth-child(10) {
    transition-delay: 1s;
}
