dynamic css per user

Question

i have a gamimng section on my site that allow the user to display a quick status of their stats using colors (blue, red, and green).

i want to generate something like this based per user. i have this so far:

<style>
.box2 {
    height: 20px;
    background: blue;
    float:left;
    width:120px;
}
.box3 {
    height: 20px;
    background: green;
    float:left;
    width:30px;
}
.box1 {
    height: 20px;
    background: red;
    float:left;
    width:140px;
}
</style>

<div>
    <div class="box1"></div>
    <div class="box2"></div>
    <div class="box3"></div>
</div>

should i put the css directly in the page? what will be the best way to implement this using php?

Answer 1

You can always use a generated file using PHP and include it as your CSS file like:

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

Then in this file you can use the current session to find out the user stats then generate using PHP. Don't forget the put the header:

header("Content-type: text/css");

Example php:

background: #<?php echo $colorX; ?>; // assuming the $colorX is HEX

You can also if you prefer use .htaccess to rewrite the file so it looks less obvious like:

RewriteEngine On
RewriteBase /
RewriteRule ^css/userstats.css$ /path/to/generatedfile.php [L,NC]

So you can use:

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

example code:

<style>
div.bar {
    height: 25px;
}
div.bar div {
    display: block;
    float:left;
    height: 25px;
    margin: 0;
    padding: 0;
    position: relative;
}
div.bar div.red {
    background: #DD3030;
    -webkit-box-shadow: -5px 0px 8px 2px #DD3030;
    -moz-box-shadow: -5px 0px 8px 2px #DD3030;
    box-shadow: -5px 0px 8px 2px #DD3030;
    width:140px;
    -moz-border-radius-topleft: 8px;
    -moz-border-radius-topright: 0px;
    -moz-border-radius-bottomright: 0px;
    -moz-border-radius-bottomleft: 8px;
    -webkit-border-radius: 8px 0px 0px 8px;
    border-radius: 8px 0px 0px 8px;
    z-index:10;
}
div.bar div.blue {
    background: #3388DD;
    -webkit-box-shadow: 0px 0px 8px 2px #3388DD;
    -moz-box-shadow: 0px 0px 8px 2px #3388DD;
    box-shadow: 0px 0px 8px 2px #3388DD;
    width:120px;
    z-index:5;
}
div.bar div.green {
    background: #1CAD32;
    -webkit-box-shadow: 5px 0px 8px 2px #1CAD32;
    -moz-box-shadow: 5px 0px 8px 2px #1CAD32;
    box-shadow: 5px 0px 8px 2px #1CAD32;
    width:30px;
    -moz-border-radius-topleft: 0px;
    -moz-border-radius-topright: 8px;
    -moz-border-radius-bottomright: 8px;
    -moz-border-radius-bottomleft: 0px;
    -webkit-border-radius: 0px 8px 8px 0px;
    border-radius: 0px 8px 8px 0px;
    z-index:10;
}
</style>

<div class="bar">
    <div class="red"></div>
    <div class="blue"></div>
    <div class="green"></div>
</div>
