I have a little question. Can I dynamically change (with php) content of the css style in this way?
<?php
header("Content-type: text/css; charset: UTF-8");
$color = "red;";
?>
header {
color:<?php print $color; ?>
}
?>
.phpor use.htdocsto parse.cssfiles as PHP. As for cache, you just need to set that within headers.
