There are a lot of ways that you could do this. One way would be to use sessions to store some info.

You can use a form like this one...

<form id="theme" action="" method="post">

<p>

 <select name="Color">

  <option>please select a Color ...</option>

  <option value="green">Green</option>

  <option value="blue">Blue</option>

  <option value="orange">Orange</option>

  <option value="purple">Purple</option>

 </select>



 <select name="Font">

  <option>please select a Font ...</option>

  <option value="green">Green</option>

  <option value="blue">Blue</option>

  <option value="orange">Orange</option>

  <option value="purple">Purple</option>

 </select>

<input type="submit" value="Change Theme">

</p>

</form>

Then place the following lines at the top of each php page....

<?

 session_start();



if(isset($_POST['Font']))  {$_SESSION['Font']        = $_POST['Font'];}

if(isset($_POST['Color']))  {$_SESSION['Color']        = $_POST['Color'];}



?>

Then in your <head> section echo your css theme....

<? 

echo "<style type 'text/css'>";



echo "p {color: ".$_SESSION['Color']." font-size: ".$_SESSION['Font']."}"; ?>

echo "</style>";

You would have to echo the session color and font throughout your css file.
You could also have predefined styles and use a similar session result.

Please note: I haven't tested this, but I think it might work.

There are probably better ways of doing this, but hope it helps.
