I split my body content in two parts. The left one has a map and buttons. When I click on the button, I get the result from Arad.php in another window.
How can I set the target to the second half (split right) of my body?
<body> 
    <div class="split left">
        <div class="centered">    
            <h2>Button on Image</h2>
            <p>Add a button to an image:</p>
            <div class="container">
                <img src="Harta_Romaniei.jpg" alt="Harta_Romaniei" style="width:100%">
                <button class="btnarad"; onclick= "window.location.href='Arad.php'"; Target="split right">Arad</button>
                <button class="btntimisoara">Timisoara</button>
            </div>        
        </div>
    </div>
    <div class="split right">
      <div class="centered">
        <h2>Information</h2>
        // I want the information here!
        </div>
    </div>
</body>
