Understanding Unused CSS and its Impact on Website Performance

Unused CSS refers to the CSS code that is loaded on a webpage but is not actually used or applied to any elements on that page. This can happen when themes or templates contain excessive CSS styles that are not utilized by the specific pages of your Shopify store.

The presence of unused CSS can have a significant impact on your website’s performance. If there is unnecessary CSS code, it adds unnecessary weight to the page, resulting in increased load times. 

Why Unused CSS Optimization is Important for Shopify Stores

There are several reasons why unused CSS is determined to shopify stores and websites in general:

  • Unused CSS optimization is particularly important for Shopify stores. It offers a wide range of themes and templates that you can customize to create your store’s unique look and feel. However, these themes often come with pre-designed styles and CSS code that may not be relevant to your specific store.
  • When you install a theme or template on your Shopify store, it automatically includes the entire CSS file associated with that theme, even if you’re only using a fraction of the styles. This means that your store could be loading unnecessary CSS code, which can negatively impact performance.

Tools and Techniques for Identifying Unused CSS

Identifying unused CSS can be a challenging task, especially if you have a large and complex Shopify store. Fortunately, there are several tools and techniques available to help you in this process.

  • One popular tool for identifying unused CSS is the “Coverage” feature in Google Chrome’s DevTools. This tool allows you to analyze which CSS rules are used and which ones are not on a particular page. By running a coverage report, you can easily identify the unused CSS and take the necessary actions to optimize it.
  • Manual inspection and code analysis can also be effective in identifying unused CSS. By thoroughly reviewing your theme’s CSS files and comparing them with the actual elements used on your store’s pages, you can manually identify and remove unnecessary styles.

Now that you understand the importance of unused CSS optimization for your Shopify store, let’s dive into a step-by-step process on how to optimize it effectively.

Step 1: Analyze your store’s CSS files: Start by analyzing your store’s CSS files to get an overview of the styles used throughout your website. You can use tools like “Coverage” in Google Chrome’s DevTools or automated solutions like “PurgeCSS” to generate a list of unused CSS.

Step 2: Identify unused styles: Once you have generated the list of unused CSS, review it to identify the styles that are not used on any pages of your store. This can be done manually or using automated tools.

Step 3: Remove unused CSS: Once you have identified the unused styles, remove them from your CSS files. Make sure to create a backup of your original CSS files before making any changes.

Step 4: Test and validate: After removing the unused CSS, thoroughly test your store to ensure that there are no visual or functional issues. Validate the changes across different devices and browsers to guarantee a seamless experience for your customers.
