Technical FAQ
Why use CSS instead of GIFs or JS?
CSS loaders are vector-based, retina-ready, and don't require extra HTTP requests. They also allow you to change colors dynamically using CSS variables.
How do I center the loader?
The easiest way is using Flexbox: 'display: flex; justify-content: center; align-items: center;' on the parent container.
