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.

What is 'render-blocking CSS'?
Jun 24, 2025 am 12:42 AM
CSS blocks page rendering because browsers view inline and external CSS as key resources by default, especially with imported stylesheets, header large amounts of inline CSS, and unoptimized media query styles. 1. Extract critical CSS and embed it into HTML; 2. Delay loading non-critical CSS through JavaScript; 3. Use media attributes to optimize loading such as print styles; 4. Compress and merge CSS to reduce requests. It is recommended to use tools to extract key CSS, combine rel="preload" asynchronous loading, and use media delayed loading reasonably to avoid excessive splitting and complex script control.

CSS: When Does Case Matter (and When Doesn't)?
Jun 19, 2025 am 12:27 AM
In CSS, selector and attribute names are case-sensitive, while values, named colors, URLs, and custom attributes are case-sensitive. 1. The selector and attribute names are case-insensitive, such as background-color and background-Color are the same. 2. The hexadecimal color in the value is case-sensitive, but the named color is case-sensitive, such as red and Red is invalid. 3. URLs are case sensitive and may cause file loading problems. 4. Custom properties (variables) are case sensitive, and you need to pay attention to the consistency of case when using them.
