Pros of SpinKit

• Offers a wider variety of loading animations (11 types)
• Includes SASS source files for easier customization
• Provides better browser compatibility, including support for older versions

Cons of SpinKit

• Larger file size due to more complex animations
• Requires more markup for some animations, potentially increasing HTML complexity
• Less focused on minimalism compared to Three Dots

Code Comparison

SpinKit (HTML):

<div class="sk-chase">
  <div class="sk-chase-dot"></div>
  <div class="sk-chase-dot"></div>
  <div class="sk-chase-dot"></div>
  <div class="sk-chase-dot"></div>
  <div class="sk-chase-dot"></div>
</div>

Three Dots (HTML):

<div class="dot-pulse"></div>

SpinKit focuses on providing a wide range of complex loading animations with extensive browser support. It offers more customization options through SASS files but requires more markup for some animations. Three Dots, on the other hand, emphasizes simplicity and minimalism, with fewer animation options but cleaner HTML structure. The code comparison demonstrates the difference in markup complexity between the two libraries for similar loading animations.

Pros of css-loaders

• Offers a wider variety of loader styles (11 different types)
• Includes more complex animations like rotating squares and pulsing circles
• Provides single-element CSS solutions for each loader type

Cons of css-loaders

• Less customization options for individual loaders
• Larger file size due to more complex animations and variety
• Some loader styles may be more resource-intensive

Code Comparison

css-loaders:

.loader {
  border: 16px solid #f3f3f3;
  border-top: 16px solid #3498db;
  border-radius: 50%;
  width: 120px;
  height: 120px;
  animation: spin 2s linear infinite;
}

three-dots:

.dot-pulse {
  position: relative;
  left: -9999px;
  width: 10px;
  height: 10px;
  border-radius: 5px;
  background-color: #9880ff;
  color: #9880ff;
  box-shadow: 9999px 0 0 -5px;
  animation: dot-pulse 1.5s infinite linear;
  animation-delay: 0.25s;
}

Both repositories provide CSS-based loading animations, but they differ in approach and complexity. css-loaders offers a wider range of styles with more intricate animations, while three-dots focuses on simpler, customizable dot-based loaders. The code comparison shows that css-loaders tends to use more straightforward CSS properties, while three-dots employs more advanced techniques like box-shadow and relative positioning for its animations.

Pros of loaders.css

• Offers a wider variety of loader animations (42 different types)
• Includes both CSS and Sass versions for flexibility
• Provides a live demo page for easy visualization of all loaders

Cons of loaders.css

• Larger file size due to more animations
• Less focused on a specific style, which may lead to inconsistency in design
• Hasn't been updated since 2016, potentially outdated

Code Comparison

three-dots:

.dot-elastic {
  position: relative;
  width: 10px;
  height: 10px;
  border-radius: 5px;
  background-color: #9880ff;
  animation: dotElastic 1s infinite linear;
}

loaders.css:

.ball-pulse > div {
  width: 15px;
  height: 15px;
  border-radius: 100%;
  margin: 2px;
  animation-fill-mode: both;
  display: inline-block;
  animation: scale 0.75s 0.12s infinite cubic-bezier(.2,.68,.18,1.08);
}

Both repositories provide CSS-based loading animations, but they differ in scope and implementation. three-dots focuses on simple, minimalistic dot animations, while loaders.css offers a broader range of loader styles. The code snippets show that three-dots uses a single element for animation, whereas loaders.css often employs multiple elements for more complex animations.

Pros of loading

<div class="dot-elastic"></div>

@import 'three-dots/dist/three-dots.min.css';

Summary

loading is a React-specific library offering simple, lightweight loading animations with various styles. It's easy to use but less actively maintained. three-dots provides CSS-based loading animations that can be used in any web project, offering more customization options and regular updates. The choice between them depends on your project's requirements and preferred technology stack.
