Installation

NOTE: All basic card styles like padding, border radius, font, font size and flex alignment for card content has been removed from V3.0.0 to make it more customizable. You can add your own styles to the card using various style props in both <Flashcard /> and <FlashcardArray /> components or by defining the styles in cards array as mentioned below.

Basic Usage

import { FlashcardArray } from "react-quizlet-flashcard";

function App() {
  const cards = [
    {
      id: 1,
      frontHTML: <div>What is the capital of <u>Alaska</u>?</div>,
      backHTML: <>Juneau</>,
    },
    {
      id: 2,
      frontHTML: <>What is the capital of California?</>,
      backHTML: <>Sacramento</>,

        backHTML={<h1>Back</h1>}
        manualFlipRef={flipRef}

    </div>
  );
}

Cards with custom controls(Using forwardRef prop):

import { FlashcardArray } from "react-quizlet-flashcard";
import { useRef } from "react";

function App() {
  const controlRef = useRef({}); // {} should definitely be passed to useRef for it to work
  const currentCardFlipRef = useRef(); // nothing should be passed to useRef for it to work
  const [currentCard, setCurrentCard] = useState(1);

  return (
    <div className="storyContainer">
      <FlashcardArray
        cards={deck.cards}
        controls={false}
        showCount={false}
        forwardRef={controlRef}
        currentCardFlipRef={currentCardFlipRef}
        onCardChange={(id, index) => {
          setCurrentCard(index);
        }}
      />
      <p>
        {currentCard} / {deck.cards.length}

      />

    <div className="storyContainer">
      <FlashcardArray
        cards={[

            frontHTML: (
              <>

              </>
