nth-child(),在style样式中写多个nth-child(),只有样式中第一个nth-child()样式生效,求教

<!DOCTYPE html>
<html lang="en">
<head>
  <meta charset="UTF-8">
  <meta name="viewport" content="width=device-width, initial-scale=1.0">
  <title>Document</title>
  <style>
    .third_cols_table tbody tr td:nth-child(1) {
      color: red;
    };
    .third_cols_table tbody tr td:nth-child(2) {
      color: aqua;
    };
    .third_cols_table tbody tr td:nth-child(3) {
      color: blue;
    };
  </style>
</head>
<body>
  <div>
    <table class="third_cols_table">
    <tr>
      <td>名称</td>
      <td>数量</td>
      <td>单价</td>
    </tr>
  </table>
  </div>
</body>
</html>

就第一个td 变红,其他td没反应,我真的没明白到底为啥??????

有可能是因为你在花括号后面加了分号

.third_cols_table tbody tr td:nth-child(1) {
  color: red;
}
.third_cols_table tbody tr td:nth-child(2) {
  color: aqua;
}
.third_cols_table tbody tr td:nth-child(3) {
  color: blue;
}
