Unused CSS finder VS User CSS

Crawl your website and find unused CSS

User CSS is a browser extension that allows you to inspect style sheets from websites.

Efficiency
Identifies unused CSS, resulting in cleaner and more efficient code. This can lead to improved page load times and reduced bandwidth usage.
Ease of Use
Provides a straightforward interface that allows users to quickly scan their websites and find unnecessary CSS without needing extensive technical knowledge.
Cost Savings
By eliminating unused CSS, it reduces the amount of data that needs to be transmitted and stored, potentially saving on hosting and bandwidth costs.
Improved Maintenance
With a reduction in CSS file size, future maintenance becomes easier and more manageable, making it simpler to update or refactor code.

False Positives
May incorrectly identify CSS as unused if the tool does not recognize dynamic changes or conditional loading, which can lead to accidental removal of necessary styles.
Dependency on External Tool
Relying on an external tool could present privacy and security concerns, especially when sharing potentially sensitive code and styling information.
Manual Verification
Requires manual verification of results to ensure important styles are not removed, which can be time-consuming and somewhat negate the tool's time savings.
Incompatibility with Complex Frameworks
Might not effectively handle complex CSS frameworks or preprocessors, where styles are used indirectly or dynamically through Javascript or server-side frameworks.

Customization
User CSS allows for extensive customization of the appearance of websites, enabling users to tailor styles to their preferences or needs.
Accessibility
Custom styles can improve accessibility by enhancing contrast, increasing font sizes, or adjusting layouts to make content more readable for individuals with visual impairments.
Consistency
It can create a consistent look and feel across different websites by applying a personalized style sheet, which is beneficial for users who value uniformity.
Ad Blocking
User CSS can be used to hide unwanted elements like advertisements or pop-ups, creating a cleaner browsing experience.
Focus on Content
Users can modify the display to focus on content they deem important by hiding or de-emphasizing less relevant elements.

Maintenance
User CSS scripts need regular updates and maintenance, as changes to website structures, class names, or IDs can break the applied styles.
Compatibility Issues
Custom styles may not render correctly across different devices or browsers, leading to inconsistencies in how content is viewed.
Complexity
For non-technical users, creating and managing User CSS can be complex and daunting without knowledge of CSS.
Website Functionality
Incorrect or overly aggressive styling can inadvertently break website functionality or usability by hiding functional elements such as navigation or interactive components.
Performance
Applying User CSS can affect the loading performance of websites, especially if the styles are extensive or poorly optimized.
