如何将表单拆分为两列？

Question

我有一个基本的表单,将输入传递给PHP脚本.我想拆分表单,以便第二个子条目(Person 2)位于第一个(Person 1)右侧的列中,而不是直接位于下面.

<link rel="stylesheet" href="test.css">    
    <form class="form-validation" method="post" action="script.php">
       <link rel="stylesheet" href="test.css">
       <h2>Person 1:</h2>
       <br>
       <div class="form-row form-input-name-row">
          <label>
          <span>Name</span>
          <input name="field1" type="text">
          </label>
       </div>
       <div class="form-row form-input-name-row">
          <label>
          <span>Age</span>
          <input name="field2" type="text">
          </label>
       </div>
       <div class="main-content">
          <h2>Person 2:</h2>
          <br>
          <div class="form-row form-input-name-row">
             <label>
             <span>Name</span>
             <input name="field3" type="text">
             </label>
          </div>
          <div class="form-row form-input-name-row">
             <label>
             <span>Age</span>
             <input name="field4" type="text">
             </label>
          </div>
    </form>
    <div>
    <button name="submit">Submit form</button>
    </div>
    </div>

将两个条目包装在具有相同类（例如“子条目”）的 div 中，并将它们向左浮动，宽度为 50%：

.sub-entry {
    width: 50%;
    float: left;
}

.button {
    text-align: center;
    padding-top: 20px;
    clear: both;
}

<form class="form-validation" method="post" action="script.php">
    <link rel="stylesheet" href="test.css">
    <div class="sub-entry">
        <h2>Person 1:</h2>
        <br>
        <div class="form-row form-input-name-row">
            <label>
                <span>Name</span>
                <input name="field1" type="text">
            </label>
        </div>
        <div class="form-row form-input-name-row">
            <label>
                <span>Age</span>
                <input name="field2" type="text">
            </label>
        </div>
    </div>
    <div class="sub-entry">
        <div class="main-content">
            <h2>Person 2:</h2>
            <br>
            <div class="form-row form-input-name-row">
                <label>
                    <span>Name</span>
                    <input name="field3" type="text">
                </label>
            </div>
            <div class="form-row form-input-name-row">
                <label>
                    <span>Age</span>
                    <input name="field4" type="text">
                </label>
            </div>
        </div>
    </div>
</form>
<div class="button">
    <button name="submit">Submit both forms</button>
</div>

请注意，我还为包含该按钮的 div 提供了一个类按钮，并将其样式设置为表单的中心。
