Reduce unused CSS

Unused CSS can negatively impact website performance by increasing page load times, so it’s important to reduce it as much as possible. Here are some ways to do that:

1. Use a tool to identify unused CSS: There are several tools available, such as PurifyCSS and UnCSS, that can analyze your website and identify CSS that is not being used.
2. Remove unused CSS manually: If you don’t want to use a tool, you can manually go through your CSS and remove any styles that are not being used on your website.
3. Use a CSS preprocessor: CSS preprocessors, such as Sass and Less, allow you to write more modular CSS and avoid writing redundant styles.
4. Use inline styles: Inlining styles can reduce the amount of unused CSS that needs to be loaded, especially for small websites or individual pages.
5. Load CSS dynamically: You can also use JavaScript to load CSS files dynamically based on the needs of each page, rather than loading all stylesheets on every page.

Remember that reducing unused CSS is not a one-time task, and it should be done regularly to ensure that your website is performing at its best.
