What Are Loaders & Spinners Components?
CSS loading animations are visual indicators shown while content is being fetched or processed. UIsen provides free spinners, skeleton loaders, pulse animations, progress bars, and creative loading effects — all built with pure CSS.
Loading animations are essential for perceived performance. Research shows that skeleton screens can make users perceive load times as 30% shorter than traditional spinners. UIsen's loader collection includes rotating spinners, bouncing dots, skeleton screens, gradient wave loaders, orbit animations, and creative text-based loading indicators. Every loader is lightweight (under 2KB) and uses pure CSS animations with no JavaScript dependencies.
Types of Loaders & Spinners
Spinners
Rotating circle or ring animations using CSS border and transform: rotate().
Skeleton Loaders

Pulse Animations
Pulsating dots or shapes using CSS @keyframes scale and opacity animations.

Frequently Asked Questions
Which is better: skeleton loader or spinner?
Skeleton loaders are generally better for perceived performance. Facebook/Meta research found that skeleton screens make users perceive load times as approximately 30% shorter than spinners. Use skeleton loaders for content-heavy pages and spinners for short, indeterminate waits under 2 seconds.
How do I create a CSS-only loading spinner?
Create a div with a border on three sides and a transparent fourth side. Apply border-radius: 50% to make it circular, then use @keyframes rotate { to { transform: rotate(360deg) } } with animation: rotate 1s linear infinite. This creates a smooth spinning animation with no JavaScript.
Do CSS loaders affect page performance?
Well-built CSS loaders have minimal performance impact. Use transform and opacity for animations (GPU-accelerated), avoid animating layout properties like width/height, and keep the DOM structure simple. UIsen loaders average under 2KB and use only CSS properties that are composited by the browser.
