Both have minimal UI and supporting messages are generally displayed to describe the input. Radio buttons are used in the group i.e. if one of them is checked, rest will be unchecked automatically.

I found this jquery plugin which apply styles to Check boxes and Radio buttons for presenting better interface. I liked it because it makes the selected choice more clear to the user. You can find this plug-in at http://widowmaker.kiev.ua/checkbox/. Project is also hosted at google code so you can also check http://code.google.com/p/jquery-checkbox/

Some of the features:

1. Only inline elements used, just like default checkoxes
2. Cross-browser look and feel (tested in IE6, IE7, IE8, Firefox and Chrome engines)
3. Work with radio buttons too
4. Supports inline and jQuery attached click events
5. Dynamic skin changing
6. Adds new checkbox events “check”, “uncheck”, “disable”, “enable”, ready to use in jQuery.bind() method

And of course there is a dependency of Jquery javascript library(1.3.2 recommended) .

Now here is the code using which above check boxes and Radio buttons are transformed.

 
$(document).ready(function() {
	$('input:checkbox').checkbox();
	$('input:radio').checkbox();
});
 
 

Above code will add style to all the check box and radio inputs present in document.

In case you need to have different pages for different browsers, You can use a module on httpd for it i.e. mod rewrite. You can re-write the URL by checking the browser so that every browsers will be pointed to page specific to it.

Here is an example for how to configure it:

RewriteCond %{HTTP_USER_AGENT}  Opera
RewriteRule ^index.html http://www.mywebsite.com/index-opera.html [R]
RewriteCond %{HTTP_USER_AGENT} MSIE
RewriteRule ^index.html http://www.mywebsite.com/index-IE.html [R]
RewriteCond %{HTTP_USER_AGENT} Firefox
RewriteRule ^index.html http://www.mywebsite.com/index-firefox.html [R]

Use it, in case you need different pages for different browsers and Of course you need to enable this module before using it.
