Currently, I am working on a project where users have the ability to interactively change the background color of a page by clicking on a specific button. While searching through various resources, I noticed that most tutorials focus on how to change the background color of text boxes or grid views, rather than the entire page. This feature is similar to customization tools found on popular sites such as Orkut and Facebook.
When it comes to styling in the css/style.
body
{
background-color:#000000;
}
If you prefer changing the color dynamically, consider updating the body class using javascript or code behind to apply a different background color.
For example, in the code behind, ensure you have the body element with runat="server" and an id attribute:
bodyId.Attributes["class"] = "test";
In the CSS stylesheet:
.test
{
background-color: #000000 !important;
}
Keep in mind that this change will be applied after a postback, while the websites you mentioned likely use JavaScript for instant updates.
If you want to dynamically modify the DOM, using jQuery can be a great solution for your needs. Take a look at this example that utilizes the .css() method from jQuery. Once you implement this change, you can save the value in a cookie or another storage method for future use when the page reloads.
//assuming that MyButtonId is the ID of the button being clicked
$('#MyButtonId').click(function () {
//change the background-color of the body to green
$('body').css('background-color', '#00F')
});
