I have a basic form which passes input to a PHP script. I'd like to split the form up so that the second sub-entry (Person 2) sits in a column to the right of the first (Person 1), rather than directly below.
<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>
