What is a common way to enhance theme performance?

Minifying CSS and JavaScript files is a widely recognized method for enhancing theme performance. This process involves removing unnecessary characters from the code, such as white spaces, comments, and formatting that do not affect functionality. By streamlining the size of the CSS and JavaScript files, the overall loading time of the web page is reduced. Smaller file sizes lead to faster downloads, which can significantly improve user experience and site speed—critical factors for both SEO rankings and customer satisfaction.

In contrast, loading all images at once can lead to longer loading times and negatively impact performance, while using high-resolution images exclusively may also contribute to slower loading times due to their larger file sizes. Adding multiple scripts for every feature can complicate the page and increase loading times as well since each additional script may require its own request to load, further slowing down the overall performance of the theme. Therefore, focusing on minification is a strategic way to ensure that the codebase is efficient and allows for quicker rendering of the webpage.
