jQuery SVG: Overcoming the Class Manipulation Obstacle
Incorporating jQuery into your SVG operations can streamline development. However, a common pitfall encountered is the inability to add or remove classes from SVG elements. Let's delve into the issue and explore solutions.
The Problem:
When attempting to manipulate classes in an SVG element using jQuery, it often fails. For instance, consider the following code:
<svg> <rect>
In this example, the jQuery code should add the "clicked" class to the rectangle when clicked. However, it fails to do so.
The Solution:
1. Utilize JQuery 3 or Later:
JQuery versions prior to 3 encountered difficulties when working with SVG classes. However, this issue has been resolved in JQuery 3 and above. Upgrading to the latest JQuery version should resolve the problem.
2. Employ Vanilla JavaScript:
If you prefer not to rely on JQuery, you can manipulate SVG classes directly using vanilla JavaScript. The classList.add() method offers a convenient way to achieve this:
var element = document.getElementById("p5");
element.classList.add("clicked");
3. Leverage the .attr() Method:
Another option is to use the .attr() method, which is compatible with both jQuery and vanilla JavaScript:
// jQuery
$("#p5").attr("class", "clicked");
// Vanilla JavaScript
element.setAttribute("class", "clicked");
By utilizing one of these solutions, you can effectively manipulate classes in your SVG elements using jQuery or vanilla JavaScript, overcoming the previous limitations.

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.

What is the scope of a CSS Custom Property?
Jun 25, 2025 am 12:16 AM
The scope of CSS custom properties depends on the context of their declaration, global variables are usually defined in :root, while local variables are defined within a specific selector for componentization and isolation of styles. For example, variables defined in the .card class are only available for elements that match the class and their children. Best practices include: 1. Use: root to define global variables such as topic color; 2. Define local variables inside the component to implement encapsulation; 3. Avoid repeatedly declaring the same variable; 4. Pay attention to the coverage problems that may be caused by selector specificity. Additionally, CSS variables are case sensitive and should be defined before use to avoid errors. If the variable is undefined or the reference fails, the fallback value or default value initial will be used. Debug can be done through the browser developer
