How to measure and improve performance of CSS rendering

Measuring and improving the performance of CSS rendering is crucial for achieving faster web page load times and enhancing user experience. Here are some steps you can take to analyze and optimize the CSS rendering process:

Ways to Measure CSS Performance:

  • Use browser developer tools to analyze render times and repaint events.
  • Employ tools like Lighthouse to get insights on CSS performance.
  • Monitor the Critical Rendering Path to understand CSS impact on page load speed.

Techniques to Improve CSS Rendering:

  • Minimize CSS file size by removing unused styles.
  • Use asynchronous loading for non-critical CSS.
  • Combine and compress CSS files to reduce HTTP requests.
  • Leverage caching strategies for CSS files.
