how do i implement themes like ask.com to my websites? Should i be using Ajax, according to one of my friend it is done using JQuery? Also it will be a great help if someone can redirect me to a tutorial (asp.net and/or php). Thanks.
W3Schools has many good tutorials for starters.
As for your query regarding Ask.com, you can build something similar using jQuery. You may just need to change the style when peel is clicked. For example:
$('.peel').click(
function() {
$('.container').css( 'background-image', 'http://url/to/image/' );
}
);
there are ways lol :)
you could use jquery. or you could use js however you still need the power of css on this. you would first have a default theme default.css then a optional theme optional.css
then you would have to change the source of your < script > tag
other wise if you really understand javascript and html
check this page out... http://jqueryui.com/themeroller/ then check the gallery button. see how they do it there.
but it sounds like you are not experienced and i think you are trying to run before you can walk. Learn the basics of html and javascript on w3schools.com then you should be good to go they have amazing tutorials there
