Animated Colorful Card in Vanilla JavaScript

This lightweight Vanilla JavaScript code snippet helps you to create colorful animated card. The cards come with various colors and display on the click event with expanding animation.

How to Create Animated Colorful Card in Vanilla JavaScript

1. First of all, load the Normalize CSS into the head tag of your HTML document:

<link rel="stylesheet" href="https://cdnjs.cloudflare.com/ajax/libs/normalize/5.0.0/normalize.min.css">

2. After that, create the HTML structure for colorful cards as follows:

<div class="block-wrap">
  <div class="block-col">
    <div class="block block--transition r">
      <div class="block-content">
        <div class="block-content__header">
          <h2 class="block-content__header__text">Red</h2>
        </div>
        <p class="block-content__body">Red is the color at the end of the visible spectrum of light, next to orange and opposite violet. It has a dominant wavelength of approximately 625–740 nm.</p>
        <div class="block-content__button">
          Neato
        </div>
      </div>
    </div>
  </div>
  <div class="block-col">
    <div class="block block--transition  b">
      <div class="block-content">
        <div class="block-content__header">
          <h2 class="block-content__header__text">Blue</h2>
        </div>
        <p class="block-content__body">Blue is one of the three primary colours of pigments in painting and traditional colour theory, as well as in the RGB colour model. It lies between violet and green on the spectrum of visible light.</p>
        <div class="block-content__button">
          Very Cool
        </div>
      </div>
    </div>
  </div>
  <div class="block-col">
    <div class="block block--transition y">
      <div class="block-content">
        <div class="block-content__header">
          <h2 class="block-content__header__text">Yellow</h2>
        </div>
        <p class="block-content__body">Yellow is the color between orange and green on the spectrum of visible light. It is evoked by light with a dominant wavelength of roughly 570–590 nm. It is a primary color in subtractive color systems.</p>
        <div class="block-content__button">
          Yikes this one's low contrast
        </div>
      </div>
    </div>
  </div>
</div>

3. Style the cards using the following CSS:

  box-sizing: border-box;
}

  -webkit-animation-delay: 0.1s;
          animation-delay: 0.1s;
  margin: 0 0 20px;
}

.block-content__button {
  font-weight: bold;
  background: rgba(255, 255, 255, 0.25);
  display: inline-block;
  padding: 16px;
  border-radius: 4px;
  color: rgba(255, 255, 255, 0.85);
  -webkit-animation: button-in 0.245s cubic-bezier(0, 0, 0.2, 1) forwards;
          animation: button-in 0.245s cubic-bezier(0, 0, 0.2, 1) forwards;
  -webkit-animation-delay: 0.2s;
          animation-delay: 0.2s;
  opacity: 0;

}

@-webkit-keyframes content-in {
  0% {
    opacity: 0;
    transform: translateY(128px);
  }
  100% {
    opacity: 1;
    transform: translateY(0);
  }
}

@keyframes content-in {
  0% {
    opacity: 0;
    transform: translateY(128px);
  }
  100% {
    opacity: 1;
    transform: translateY(0);
  }
}
@-webkit-keyframes button-in {
  0% {
    opacity: 0;
    transform: translateY(64px);
  }
  100% {
    opacity: 1;
    transform: translateY(0);
  }
}
@keyframes button-in {
  0% {
    opacity: 0;
    transform: translateY(64px);
  }
  100% {
    opacity: 1;
    transform: translateY(0);
  }
}
.r {
  background: #f44336;
  color: #410804;
  border-top: 2px solid #f77066;
}
.r:not(.block--active) {
  border-bottom: 2px solid #ea1c0d;
  box-shadow: 0 8px 8px -8px #d2190b, 0 12px 12px -8px rgba(244, 67, 54, 0.4);
}
.r.block--active {
  background: #faf0ef;
}
.r .block-content__header {
  background: #f44336;
}
.r .block-content__button {
  background: #f44336;
  border-bottom: 2px solid #ea1c0d;
  border-top: 2px solid #f77066;
}

.b {
  background: #1e88e5;
  color: #03101a;
  border-top: 2px solid #4ca0ea;
}
.b:not(.block--active) {
  border-bottom: 2px solid #166dba;
  box-shadow: 0 8px 8px -8px #1360a4, 0 12px 12px -8px rgba(30, 136, 229, 0.4);
}
.b.block--active {
  background: #d5e2ed;
}
.b .block-content__header {
  background: #1e88e5;
}
.b .block-content__button {
  background: #1e88e5;
  border-bottom: 2px solid #166dba;
  border-top: 2px solid #4ca0ea;
}

.y {
  background: #fdd835;
  color: #4c3e01;
  border-top: 2px solid #fee268;
}
.y:not(.block--active) {
  border-bottom: 2px solid #fdce03;
  box-shadow: 0 8px 8px -8px #e3ba02, 0 12px 12px -8px rgba(253, 216, 53, 0.4);
}
.y.block--active {
  background: #fcfbf5;
}
.y .block-content__header {
  background: #fdd835;
}
.y .block-content__button {
  background: #fdd835;
  border-bottom: 2px solid #fdce03;
  border-top: 2px solid #fee268;
}

4. Finally, add the following JavaScript function to activate the card expanding animation.

const ACTIVE_CLASS = "block--active";
const TRANSITION_CLASS = "block--transition";

const getTransforms = (a, b) => {
  const scaleY = a.height / b.height;
  const scaleX = a.width / b.width;

  // dividing by 2 centers the transform since the origin
  // is centered not top left
  const translateX = a.left + a.width / 2 - (b.left + b.width / 2);
  const translateY = a.top + a.height / 2 - (b.top + b.height / 2);

  // nothing particularly clever here, just using the
  // translate amount to estimate a rotation direction/amount.
  // ends up feeling pretty natural to me.
  const rotate = translateX;

  return [
    `translateX(${translateX}px)`,
    `translateY(${translateY}px)`,
    `rotate(${rotate}deg)`,
    `scaleY(${scaleY})`,
    `scaleX(${scaleX})`
  ].join(" ");
};

const animate = (block, transforms, oldTransforms) => {
  block.style.transform = transforms;
  block.getBoundingClientRect(); // force redraw
  block.classList.add(TRANSITION_CLASS);
  block.style.transform = oldTransforms;
  block.addEventListener(
    "transitionend",
    () => {
      block.removeAttribute("style");
    },
    { once: true }
  );
};

[...document.querySelectorAll(".block")].forEach(block => {
  const buttonForBlock = block.querySelector(".block-content__button");
  block.addEventListener("click", event => {
    if (
      block.classList.contains(ACTIVE_CLASS) &&
      event.target !== buttonForBlock
    ) {
      return;
    }

    block.classList.remove(TRANSITION_CLASS);
    const inactiveRect = block.getBoundingClientRect();
    const oldTransforms = block.style.transform;

    block.classList.toggle(ACTIVE_CLASS);
    const activeRect = block.getBoundingClientRect();
    const transforms = getTransforms(inactiveRect, activeRect);

    animate(block, transforms, oldTransforms);
  });
});

That’s all! hopefully, you have successfully created animated colorful card. If you have any questions or suggestions, feel free to comment below.
