Infinite Moving Cards

A customizable group of cards that move infinitely in a loop. Made with Framer Motion and Tailwind CSS.

It was the best of times, it was the worst of times, it was the age of wisdom, it was the age of foolishness, it was the epoch of belief, it was the epoch of incredulity, it was the season of Light, it was the season of Darkness, it was the spring of hope, it was the winter of despair.
Charles DickensA Tale of Two Cities
To be, or not to be, that is the question: Whether 'tis nobler in the mind to suffer The slings and arrows of outrageous fortune, Or to take Arms against a Sea of troubles, And by opposing end them: to die, to sleep.
William ShakespeareHamlet
All that we see or seem is but a dream within a dream.
Edgar Allan PoeA Dream Within a Dream
It is a truth universally acknowledged, that a single man in possession of a good fortune, must be in want of a wife.
Jane AustenPride and Prejudice
Call me Ishmael. Some years ago—never mind how long precisely—having little or no money in my purse, and nothing particular to interest me on shore, I thought I would sail about a little and see the watery part of the world.
Herman MelvilleMoby-Dick

    // rest of the code
    extend: {
      animation: {
        scroll:
          "scroll var(--animation-duration, 40s) var(--animation-direction, forwards) linear infinite",
      },
      keyframes: {
        scroll: {
          to: {
            transform: "translate(calc(-50% - 0.5rem))",
          },
        },
      },
    },

  );
 
  addBase({
    ":root": newVars,
  });
}
