If anyone wants to do it in PHP rather than ASP or Javascript I wrote
this. It seems (to me) much simpler than the javascript switcher and
is browser independent.
See it in use here: http://www.nvsc.org.uk (I know, I know - tables - naughty)
The same code goes on every page. Page is reloaded when style link is
clicked. Choice is stored in a cookie, so is retained throughout the
site. Toggles between two styles, 'large' and 'default', but might be
easily customised for more choices.
You need a PHP enabled server, and the privileges to run php scripts.
For the choice to be remembered from page to page, user must have
cookies enabled.
I will be writing a tutorial on it soon but for now the code is:
*before the html tag (Must be before any html because it can only
then set a cookie):
<?php
include("styleswitch.php");
?>
*in document head, this prints the name of the chosen stylesheet into the html:
@import "<? print $csstyle?>.css";
...or use <link> for NN4 compatibility.
*Somewhere in the document, the links which switch the style:
<span class="large">[<a title="Visually impaired people may
view this page with BIGGER text" href="<? print
$PHP_SELF."?newstyle=large"?>">larger text</a>]</span>
<span class="default">[<a title="Back to normal font size"
href="<? print $PHP_SELF."?newstyle=default"?>">normal
text</a>]</span>
*In file styleswitch.php:
<?php
//process any new request
if ($newstyle){
$csstyle=$newstyle;
setcookie("csstyle", $csstyle, time()+360000, "/", "nvsc.org.uk", 0);
}
//set to default if not specified
if ( !isset ($csstyle)){
$csstyle="default";
}
?>
In order that the link for the stylesheet your user is already using
does not show, in file large.css:
.large{display:none;}
& in default.css:
.default{display:none;}
That's all folks. Hope that wasn't too off topic.
