Fill in the blank. Defer loading of non-critical CSS by adding ______ as an argument in your require_css function call.
- { defer: true }
- { position: footer }
- { type: defer }
- { async: true }
Explanation: The correct answer is { async: true }. When dealing with non-critical CSS resources, it’s often beneficial to defer their loading to improve page loading performance. By adding the { async: true } argument in the require_css function call, you instruct the browser to load the specified CSS file asynchronously. Asynchronous loading allows the browser to continue parsing and rendering the HTML content without waiting for the CSS file to be fully downloaded and processed. This approach prevents CSS resources from blocking the rendering of the page, resulting in faster initial page load times and a better user experience. Additionally, deferring non-critical CSS loading can help prioritize the loading of critical resources, such as HTML content and essential CSS styles, leading to quicker page rendering and improved perceived performance. Overall, leveraging asynchronous loading techniques for non-critical CSS resources is a recommended practice for optimizing web page loading speed and enhancing overall performance.
