Dynamic CSS Problems

Despite looking through the forum, having problems with dynamically creating an external CSS file. Can any one explain?

Basically I currently have a CSS file:

Code:

.normal
    {
    font-family: Verdana, Arial, Helvetica, sans-serif;

    font-size:   11px;
    }

.userdef
    {
    font-family: Verdana, Arial, Helvetica, sans-serif;

    font-size:   12px;
    color:       #FF0000;
    font-weight: 800;
    }

.big
    {
    font-family: Verdana, Arial, Helvetica, sans-serif;

    font-size:   12px;
    }

I have set the site up so that the user can define there own colour of text for the userdef style, but im unsure how I can put this colour variable into the CSS file. I'm guessing I have to rename it into a .php file... but how will the browser still know its a CSS file??

Thanks very much for your help

If it is only ONE element, then it would not be wise to read/write to external files.

- Create your normal CSS, then way you like.
- In the disaply page, import it ie.
<link rel="stylesheet" href="yourcss.css" type="text/css">
- After above entry add a style tag

PHP Code:


		
			
<link rel="stylesheet" href="yourcss.css" type="text/css" />

<style type="text/css">

<!--

<?php

echo ".userdef    {color: #$user_color; }";

?>

-->

</style>



</head>

- The above declaration would override the entry in yourcss.css
- Now all you have to do is to feed $user_color ie $user_color = 'FF0000'; or get it from $_POST.

This is a quick guide. You have to work on it. Make sure you have a default value and do not pass blank to $user_color

Good luck

ps. Better still:

PHP Code:


		
			
if (isset($color))

{ $user_color = ".userdef    {color: #$color; }"; }

else {$user_color = "";}



## inside the styles:

echo $user_color;

<style type="text/css">

<!--

<?php echo $user_color; ?>

-->

</style>

All you have to do is to get $color
