Unused CSS finder features and specs

  • 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.

Possible disadvantages of Unused CSS finder

  • 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.

Principle features and specs

  • User-Friendly Interface
    Principle offers a highly intuitive and easy-to-use interface, making it accessible for both beginners and experienced designers.
  • Powerful Animation Features
    The tool supports complex animations and interactive designs, enabling designers to create rich and engaging prototypes.
  • Responsive Preview
    Principle provides real-time previews of your designs on actual devices, allowing designers to see exactly how their work will look and behave.
  • Import from Sketch and Figma
    Users can easily import designs from popular design tools like Sketch and Figma, streamlining the workflow.
  • High-Fidelity Prototyping
    Capable of producing high-fidelity prototypes that closely resemble the final product, making it ideal for user testing and presentations.

Possible disadvantages of Principle

  • Mac-Only
    Principle is exclusively available for macOS, which limits its accessibility for designers using Windows or other operating systems.
  • Cost
    The software comes with a significant price tag, potentially making it less accessible for freelancers or small teams with limited budgets.
  • Lack of Collaboration Features
    Unlike some other tools, Principle lacks advanced collaboration features, making it difficult for teams to work simultaneously on a project.
  • Limited Cloud Integration
    Principle does not offer extensive cloud integration options, which can hinder version control and file sharing across teams.
  • Learning Curve for Advanced Features
    While the basic interface is user-friendly, mastering its more advanced animation and interaction features can take time.

  • What app was used to design this animated image?
    Seeing how principle is on the list. I'm going to say principle. It's like after effect but for interface design. Source: over 2 years ago
  • A mobile shopping app we just finished
    However, I did manage to make a very simple animation with my very limited skills for another project using Principle. Source: over 2 years ago
  • How to use animations to increase conversion
    Your visitors will scan your hero image or graphic first. Take advantage of that. Create subtle animations that explain better your product or offer. How will the interface be used? How simple it is? Keep it simple. I use Principle or Figma smart animate feature. If it's too complicated for you it might be very easy for a designer. Hire one for a small gig.

  • New prototype: What if Tesla had an App Store?
    I use Figma & Principle to design & prototype, usually. I show a bit of the process on my YouTube channel, if you're interested. Source: over 3 years ago
  • I made an eyes-free gesture prototype — thoughts?
    No engineering here, just smoke & mirrors! This is a set of mockups stitched together with Principle into a prototype that runs on my iPad. It uses simple keyframing for most animations and is configured to react to different touch targets. Not a single line of code was harmed in the making of this prototype ;). Source: over 3 years ago
