About CSS Loader Generator
Ten pure-CSS loading animations with adjustable size, colour and speed. The preview is rendered from the very CSS in the output box below.
- 1
Ten pure-CSS loading animations (spinner, dots, pulse, bars, grid, orbit, flip, ripple, wave, progress). Each one outputs a `@keyframes` block plus a class rule — no SVG, GIF or JS dependency.
- 2
Keyframe names carry a `bz-` prefix (such as `bz-spin`), so pasting them into an existing project cannot collide with your own animations. Size, colour and speed update the code immediately.
- 3
The preview is rendered from **the same CSS** you copy rather than a separate mock-up, so what you see is what ships. The translucent track colour is derived from the main colour, so contrast takes care of itself when you recolour.
- 1
Pick an animation
Each of the ten shapes has its own keyframes; switching replaces the code.
- 2
Set size, colour and speed
Size drives the border thickness (one eighth of it), and speed is the animation duration in milliseconds.
- 3
Copy the CSS and add the class
Paste it into a stylesheet, then put the matching class (like `bz-spinner`) on the element that should animate.
Yes — edit the line you copied. It is plain CSS (`animation: bz-spin 900ms linear infinite;`), so swapping `linear` for `ease-in-out`, replacing `infinite` with `1`, or inserting `animation-delay: 200ms;` is entirely yours to do.
Size and sharpness: each animation is a dozen lines of CSS (about 0.3 KB) with no image request, and it stays crisp at any scale or pixel density, whereas a GIF costs tens to hundreds of KB and is limited to 256 colours. The trade-off is that CSS only draws geometric motion (rotate, scale, translate, mask) — it cannot produce an illustrated loading graphic.
