It is possible to expand a textarea only with CSS?

Question

I have a textarea with 200px of height, but when I pass that 200px with text I want to have the textarea expanded instead of keeping the 200px of height with a scroll bar.

Here's a simple, pure php and html, solution, without need for js, to make the textarea fit to size. HTML: <?php echo $sometext;?>

    = $rows)   {
    $rows = $minrows;
   }
   // Return the number of rows
   return $rows;
   }
   ?> 

`And this one is even shorter and better:

function linecount($text, $cols, $minrows=1) {
    if ($text <= '') {return $minrows;}
    $text = wordwrap($text, $cols, PHP_EOL);
    $rows = substr_count( $text, PHP_EOL )+1;
    if ($minrows >= $rows) {$rows = $minrows;}
    return $rows;
}
?>
