Use dynamic URLs to 'activate' extra CSS

    Use the query string parameters to determine which stylesheet to load.

    Basically, create a general stylesheet that is always loaded, regardless of which theme you are using. Then, put theme-specific rules into separate stylesheets and use PHP if statements to determine what markup to send to load the appropriate page.

        <link href="common.css" rel="stylesheet" type="text/css" />
        <link href="<?php echo $_GET["style"] == "iPhone" ? "iPhone" : "normal" ?>.css" rel="stylesheet" type="text/css" />

    Note, I use the if-check (the ternary operator ? :) rather than just use the string directly from the query string because I want to have a way of sending a default if the user changes the query string and makes a mistake. If you have multiple themes you want to use, you can set up a switch statement and store the appropriate filename in a variable that you reference in the link tag.

    $stylesheet = "default";
    switch ($_GET["style"]) {
        case "iPhone": $stylesheet = "iPhone";
        case "bigBold": $stylesheet = "bigBold";
    <link href="<?php echo $stylesheet; ?>.css" rel="stylesheet" type="text/css" />
    How to Use:

    To add this code into your PHP page, place the switch code at the top of the page (or, better yet, in it's own included file.

    Top of the page

    Set up your page like this:

        $stylesheet = "default";
        switch ($_GET["style"]) {
            case "iPhone": $stylesheet = "iPhone";
            case "bigBold": $stylesheet = "bigBold";
    <!DOCTYPE html>
            <link href="common.css" rel="stylesheet" type="text/css" />
            <link href="<?php echo $stylesheet; ?>.css" rel="stylesheet" type="text/css" />

    This code would need to be added to every page where you wanted to use alternate styles, so the better option is to separate this code into a file that can be included on all pages.

    As an included file

    Create a file named stylesheetSelector.php and add this code to it:

        $stylesheet = "default";
        switch ($_GET["style"]) {
            case "iPhone": $stylesheet = "iPhone";
            case "bigBold": $stylesheet = "bigBold";

    Then, in your PHP page:

    <?php include_once('stylesheetSelector.php'); ?>
    <!DOCTYPE html>
            <link href="common.css" rel="stylesheet" type="text/css" />
            <link href="<?php echo $stylesheet; ?>.css" rel="stylesheet" type="text/css" />

    Do this on all pages, then, if you ever decide to add additional themes, you can simply add the information to the stylesheetSelector.php file and it will be available on EVERY page that includes it.

    CAVEAT: This needs to be done in a .php file, or your web server needs to use PHP to handle .html files, otherwise you'll see the PHP code in cleartext (it won't be interpreted).

    You could change the CSS stylesheet depending on the querystring yes ... something like this in php :

    if ($_GET['light'] == 'on'){
       echo "<style>something here</style>";
    }else {
       echo "<style>something else</style>";

    $_GET['light'] gets the querystring value for light

    Responding to the include php file . When you use the include <'stylesheetSelector.php'>, how would you include the path within <>. Since we are using separate file kept on a server, which may not have the file in the same directory ?

    read this link about conditional css stating that it is better to check browser abilities rather than selecting based on browswer. The reason is you won't have to update or change code as browser update abilities.

    URLs are classified into two types: static and dynamic. A static URL is one in which the content of the web page remains the same as long as the changes are not hard coded within the HTML. On the other hand, a dynamic URL is one which is a result of a search within a website driven by a database running on some script.

    example of static website and dynamic website Static website has webpages with constant or fixed content which cannot be changed by the user who visits the site. Static webpages are built using the HTML code and the content is static, meaning it doesn’t change automatically until and unless the webmaster or developer makes changes.
