How to stop changing a text field from its containing div

I play with flexible layouts and shapes. I am satisfied with what I still have: it works great from mobile to wide screen; See below. (Only tested on firefox / chrome so far.)

With a width of 800 pixels, it moves the message block to the right column. The problem is that this is done using float: right and position: absolute, which means that its height ceases to affect the surrounding div. Thus, the message box sticks out.

I can (and do) improve this by adding height: 220px so that it looks fine by default. But someone can resize the text box outside the surrounding div. I find resizing text fields a wonderful feature, so I don't want to reject resizing. And overflow: auto is not a solution: the user will just swap the scroll bars for a text box for scroll bars for a div!

So, is there a way to have the outer size of the div to always contain a text box?

<html>
<head>
<style>
body{background:#fff;font-family:FreeSerif, serif;font-size:16px;margin: 0 0 0 0;}

#contactform {margin: 0 auto;width:90%;max-width:320px;border:1px #000 solid;border-radius:8px;padding:6px;}
#contactform .required:after{color:red;content:" *";}
#contactform label {display:block;}
#contactform textarea {height:120px;rows:5;min-width:90%;max-width:90%;}
#contactform input,textarea {border: 1px solid red;border-radius:8px;width:90%;height:26px;padding:2px 4px;font-family:sans;}

@media (min-width: 800px) {
#contactform {margin: 0 auto;width:640px;max-width:640px;position:relative;/*height:220px;*/}
#formsecondhalf {top:0;right:6px;position:absolute;}
#contactform textarea {height:200px;rows:8;min-height:200px;min-width:300px;max-width:300px;}
#contactform input,textarea {width: 300px;min-width:300px;max-width:300px;}
}

</style>
</head>
<body>
<div id="contactform">
<form action="" method="post">
<label for="name" class="required">Name:</label>
<input id="name">
<br/>
<label for="email" class="required">Email:</label>
<input id="email">
<br/>
<div id="formsecondhalf">
<label for="message">Message:</label>
<textarea id="message"></textarea>
</div>
<br />
<input type="submit" value="SEND">
</form>
</div>
</body>
</html>

Use float: on the right instead of completely positioning the correct area. And then wrap the div around the other fields, the float remaining, and then just clear it all.

Example

<html>
    <head>
        <style>
            body{background:#fff;font-family:FreeSerif, serif;font-size:16px;margin: 0 0 0 0;}

            #contactform {margin: 0 auto;overflow:auto;width:90%;max-width:320px;border:1px #000 solid;border-radius:8px;padding:6px;}
            #contactform .required:after{color:red;content:" *";}
            #contactform label {display:block;}
            #contactform textarea {height:120px;rows:5;min-width:90%;max-width:90%;}
            #contactform input,textarea {border: 1px solid red;border-radius:8px;width:90%;height:26px;padding:2px 4px;font-family:sans;}

            @media (min-width: 800px) {
                #contactform {margin: 0 auto;width:640px;max-width:640px;position:relative;/*height:220px;*/}
                #formsecondhalf {float:right;}
                #formfirsthalf {float:left;}
                #contactform textarea {height:200px;rows:8;min-height:200px;min-width:300px;max-width:300px;}
                #contactform input,textarea {width: 300px;min-width:300px;max-width:300px;}
            }

        </style>
    </head>
    <body>
        <div id="contactform">
            <div id="formfirsthalf">
                <form action="" method="post">
                    <label for="name" class="required">Name:</label>
                    <input id="name">
                    <br/>
                    <label for="email" class="required">Email:</label>
                    <input id="email">
                    <br/>
            </div>
            <div id="formsecondhalf">
                <label for="message">Message:</label>
                <textarea id="message"></textarea>
            </div>
            <br />
            <input type="submit" value="SEND">
                </form>
        </div>
    </body>
</html>
