Form Skeleton
Two labelled inputs, a checkbox row and a full-width button, breathing with the same curve as Tailwind's animate-pulse. A caret blinks in the first field so it reads as a form, not just boxes.
Also known as: login form skeleton, input field placeholder, form loading state.

}Tailwind CSS version
The same loader using only Tailwind's built-in animation utilities. No custom keyframes or config needed.

Customizing this loader
- Color: set
--ldr-coloron the element or a parent. Currently previewing#3b82f6. - Size: set
--ldr-size. Every dimension in the snippet is derived from it. Currently previewing64px. - Speed: change the duration on the
animationshorthand. Delays on the children are relative, so they keep their rhythm. - Accessibility: the root carries
role="status"and anaria-labelso screen readers announce the wait. The reduced-motion rule at the end slows the animation for users who asked for less motion.
