html滚动歌词

要实现滚动歌词，可以使用HTML和CSS来构建，下面是一个简单的示例：

HTML代码：

<div class="lyrics">
  <ul>
    <li class="active">Verse 1</li>
    <li>Line 1 of verse 1</li>
    <li>Line 2 of verse 1</li>
    <li>Line 3 of verse 1</li>
    <li>Line 4 of verse 1</li>
    <li>Line 5 of verse 1</li>
    <li>Line 6 of verse 1</li>
    <li>Line 7 of verse 1</li>
    <li>Line 8 of verse 1</li>
    <li>Line 9 of verse 1</li>
    <li>Line 10 of verse 1</li>
    <li class="spacer"></li>
    <li class="active">Chorus</li>
    <li>Line 1 of chorus</li>
    <li>Line 2 of chorus</li>
    <li>Line 3 of chorus</li>
    <li>Line 4 of chorus</li>
    <li>Line 5 of chorus</li>
    <li>Line 6 of chorus</li>
    <li>Line 7 of chorus</li>
    <li>Line 8 of chorus</li>
    <li>Line 9 of chorus</li>
    <li>Line 10 of chorus</li>
    <li class="spacer"></li>
    <li class="active">Verse 2</li>
    <li>Line 1 of verse 2</li>
    <li>Line 2 of verse 2</li>
    <li>Line 3 of verse 2</li>
    <li>Line 4 of verse 2</li>
    <li>Line 5 of verse 2</li>
    <li>Line 6 of verse 2</li>
    <li>Line 7 of verse 2</li>
    <li>Line 8 of verse 2</li>
    <li>Line 9 of verse 2</li>
    <li>Line 10 of verse 2</li>
    <li class="spacer"></li>
    <li class="active">Chorus</li>
    <li>Line 1 of chorus</li>
    <li>Line 2 of chorus</li>
    <li>Line 3 of chorus</li>
    <li>Line 4 of chorus</li>
    <li>Line 5 of chorus</li>
    <li>Line 6 of chorus</li>
    <li>Line 7 of chorus</li>
    <li>Line 8 of chorus</li>
    <li>Line 9 of chorus</li>
    <li>Line 10 of chorus</li>
    <li class="spacer"></li>
    <li class="active">Bridge</li>
    <li>Line 1 of bridge</li>
    <li>Line 2 of bridge</li>
    <li>Line 3 of bridge</li>
    <li>Line 4 of bridge</li>
    <li>Line 5 of bridge</li>
    <li>Line 6 of bridge</li>
    <li>Line 7 of bridge</li>
    <li>Line 8 of bridge</li>
    <li>Line 9 of bridge</li>
    <li>Line 10 of bridge</li>
  </ul>
</div>

CSS代码：

.lyrics {
  height: 300px;
  overflow: hidden;
}

.lyrics ul {
  list-style-type: none;
  margin: 0;
  padding: 0;
  position: relative;
  top: 0;
  transition: top 0.5s ease;
}

.lyrics ul li {
  height: 30px;
  line-height: 30px;
  text-align: center;
}

.lyrics ul li.active {
  color: #FF0000;
  font-weight: bold;
}

.lyrics ul li.spacer {
  height: 150px;
}

使用JavaScript来控制歌词的滚动，代码如下：

var lyrics = document.querySelector('.lyrics ul');
var lyricsHeight = lyrics.clientHeight;
var currentLine = 0;

function scrollLyrics() {
  var lineHeight = lyrics.querySelector('li').clientHeight;
  if (currentLine > 0) {
    lyrics.style.top = '-' + (currentLine - 1) * lineHeight + 'px';
  }
  currentLine++;
}

setInterval(scrollLyrics, 2000); // 每2秒滚动歌词

以上代码实现了一个简单的滚动歌词效果，可以根据需求进行修改和优化。
