Understanding CSS Loading Spinners
What is a CSS Loading Spinner?
A CSS loading spinner (also called a loader or loading indicator) is a visual animation that informs users that content is being loaded or processed. Pure CSS spinners use @keyframes animations and CSS properties like transform, opacity, and border to create animated loading effects without JavaScript. Our generator creates 16 different spinner styles, each with customizable colours, sizes, and speeds.

- Customise colours and size: Use the colour picker or HEX input to set the spinner colour. Adjust size (12px to 120px) and animation speed (0.2s to 3s) with sliders or preset buttons. For circular spinners, adjust the border thickness as well.
- Copy the code: Click "Copy Code" to copy the complete HTML + CSS code block. The output includes the HTML element structure and all CSS keyframes and class styles needed for the animation to work.

Best Practices for Loading Indicators
- Use appropriate sizes: 16-24px for inline button spinners, 32-48px for content area loaders, and 64-96px for full-page loading screens.
- Match brand colours: Use your brand colour for spinners to maintain visual consistency. Our generator lets you set any HEX colour to match your design system.
- Consider speed: Faster speeds (0.5-0.75s) feel more responsive for short loads. Slower speeds (1.5-2s) are less distracting for longer loading states. Aim for 1s as the default for most use cases.
- Pair with skeleton screens: For content-heavy pages, combine spinners with skeleton loading states to give users a sense of progress and reduce perceived wait time.
