Is there a way to control external (third-party) CSS using PHP?

I want to manage CSS for a third-party website using PHP. Let's say I want to change the font size of the website, which I will use as input from the user. Can I do it?

You could generate the entire .css file generated by PHP each time, but that lost a bit of the processor. Instead, why not just use the cascading nature of css? Make your PHP output a small piece of CSS on each page to override the font installed in the .css file:

<head>
    <link rel="stylesheet" href="styles.css" type="text/css">
    <style type="text/css">
       #some_element {
          font-size: <?php echo $user_selected_font_size ?>px;
       }
    </style>

    etc...

I would recommend that the easiest approach would be to override CSS definitions by manipulating the DOM with Javascript or (even easier!) Including a tag <style>embedded in the page that you are already creating with PHP.
