我已使用样式表中的代码尝试创建 2 列布局表单，但仍然无法正常工作。我在这里做错了吗？

我错过了什么，请帮忙！

我使用flexbox为您创建了一个示例

我已经删除了你的第一行，因为你不需要它并将 css 添加到 form 和 .row

/*--- FORM ----*/

.form-container {
  width: 100%;
}

.form-container li {
  display: block;
  float: left;
  width: 100%;
  margin: 0 auto;
}

input,
select,
textarea {
  width: 60%;
}

label {
  text-align: left;
  margin-left: 18px;
  font-size: 100%;
}

form {
  display: flex;
  flex-wrap: wrap;
}

form .row {
  width: 50%;
}

<form method="post" action="#" class="contact-form">
  <div class="row">
    <div class="col span-1-of-3">
      <ul class="form-container">
        <li class="form-features">
