You can do it using create a .php file.

Add logic to it, make it a CSS file (with .php extension).

Add header parameters in (start of file) PHP file to tell Server that this is a CSS file.

<?php
header('Content-Type: text/css');
?>

Now, include the the file as a CSS file.

e.g.

<link rel="stylesheet" href="CUSTOM_STYLES.PHP"/>

This inclusion of PHP file with CSS body in it will work as a dynamic CSS file.

You can inline this part of css into your HTML template:

<style>
#border
{
  border: <?= $settings[0]->border ?>;
}
#color
{
  color: <?= $settings[0]->color ?>;
}
</style>

Or you could generate a CSS file, when the $settings value changes (to take advantage of browser caching)
