How Can jQuery Help Dynamically Switch CSS Stylesheets?

Dynamic CSS Stylesheet Switching with jQuery

In web development, you often encounter the need to dynamically change the appearance of your website based on user input. One effective method to achieve this is by switching CSS stylesheets using JavaScript. Let's explore how to do this using jQuery.

Scenario:

Consider a scenario where you have two buttons, one labeled "Original" and the other labeled "Grayscale." When the site loads, it displays a specific theme, represented by the "style1.css" stylesheet. Upon clicking the "Grayscale" button, you want to switch to the "style2.css" stylesheet to apply a grayscale effect.

jQuery Solution:

Here's how you can dynamically switch CSS stylesheets using jQuery:

$('#grayscale').click(function (){
   $('link[href="style1.css"]').attr('href','style2.css');
});
$('#original').click(function (){
   $('link[href="style2.css"]').attr('href','style1.css');
});

Explanation:

• The first function handler captures the click event on the "Grayscale" button.
• Within the handler, we use jQuery to select the element with the "style1.css" stylesheet and change its "href" attribute to "style2.css." This effectively switches the stylesheet for the website to display in grayscale.
• The second function handler follows a similar logic but reverses the process, changing the "style2.css" stylesheet back to "style1.css" when the "Original" button is clicked.
