Possible disadvantages of IcoMoon

  • Learning Curve

  • Limited Free Icons
    While IcoMoon offers a free collection, the most extensive and high-quality icons are often locked behind a paywall.
  • Dependency on External Service
    Using IcoMoon for icon management means depending on an external web service, which can be a drawback if the service experiences downtime.
  • Licensing Confusion
    There might be some confusion regarding the licensing terms for different icons, especially when using both free and premium sets.
  • Performance Concerns
    Inclusion of too many icons from custom sets can lead to larger file sizes, potentially impacting page load times.

Possible disadvantages of KnowCSS

  • Limited Depth of Content
    KnowCSS may not cover advanced CSS topics in sufficient depth, which means experienced developers may find the resource too basic for their needs and would need to supplement with other resources.
  • Limited Community and Support
    Compared to larger platforms like MDN Web Docs or CSS-Tricks, KnowCSS has a smaller community, meaning fewer discussions, forums, or peer support for troubleshooting issues.
  • Narrow Scope
    The site focuses specifically on CSS, so users looking for a comprehensive web development learning platform covering HTML, JavaScript, and other technologies will need to use additional resources.
  • Less Frequently Updated
    Smaller niche tools like KnowCSS may not be updated as frequently as major documentation sites, potentially missing coverage of the latest CSS features and specifications.
  • Limited Real-World Project Examples
    The platform may lack complex, real-world project examples that demonstrate how CSS properties work together in practical scenarios, which can leave a gap between learning individual properties and applying them in production.

It is technically possible to replace it, but you would have to ensure its new length is fewer than its original bytes. It's really a lot of hassle for very little payoff because you need to re-do the work for each subsequent... Source: about 3 years ago
