HTML代码：

<!DOCTYPE html>
<html>
  <head>
    <meta charset=""UTF-8"" />
    <title>CSS特效：鼠标悬停效果</title>
    <link rel=""stylesheet"" href=""style.css"" />

      <li><a href=""#"">CSS特效：鼠标悬停效果</a></li>
    </ul>
    <script src=""script.js""></script>
  </body>
</html>

CSS代码如下：

{
    margin: 0;
    padding: 0;
    box-sizing: border-box;
}

body {
    display: flex;
    justify-content: center;
    align-items: center;
    height: 100vh;
    background-color: #222;
    cursor: none;
}

.cursor {
    position: fixed;
    width: 20px;
    height: 20px;
    transform: translate(-50%, -50%);
    pointer-events: none;
    opacity: 0;
    border-radius: 50%;
    background-color: #0f0;
    box-shadow: 0 0 5px #0f0,
    0 0 15px #0f0,
    0 0 30px #0f0,
    0 0 60px #0f0;
    transition: opacity 0.5s;
    z-index: 999;
}

body:hover .cursor {
    opacity: 1;
}

ul {
    display: flex;
    justify-content: center;
    align-items: center;
    flex-direction: column;
    list-style: none;
}

ul li {
    padding: 10px 0;
}

ul a {
    text-decoration: none;
    color: #bbb;
    cursor: none;
}

ul li span {
    font-size: 2.5em;
    letter-spacing: 0.05em;
    transition: 0.25s;
}

ul li:hover span {
    color: #0f0;
    text-shadow: 0 0 5px #0f0,
    0 0 15px #0f0,
    0 0 30px #0f0,
    0 0 60px #0f0,
    0 0 100px #0f0;
}

JavaScript代码如下：

let cursor = document.querySelector("".cursor"");

document.addEventListener(""mousemove"", (e) => {
  cursor.style.left = `${e.pageX}px`;
  cursor.style.top = `${e.pageY}px`;
});

document.querySelectorAll(""ul a"").forEach((text) => {
  text.innerHTML = text.innerText
    .split("""")
    .map(
      (words, i) => `<span style=""transition-delay:${i * 30}ms"">${words}</span>`
    )
    .join("""");
});
