Responsive Web Design with CSS

Introduction

In this lab, we will learn how to apply CSS properties and selectors to create visually appealing and responsive web pages. You will gain hands-on experience with the latest CSS features, including flexbox, grid, transitions, and animations. By the end of this lab, you will be able to create dynamic layouts, interactive components, and engaging user experiences using CSS.

Shifting Card

index.html and style.css have already been provided in the VM.

To create a card that shifts on hover, follow these steps:

1. Set the appropriate perspective on the .container element to allow for the shifting effect.
2. Add a transition for the transform property of the .card element.
3. Use Document.querySelector() to select the .card element and add event listeners for the mousemove and mouseout events.
4. Use Element.getBoundingClientRect() to get the x, y, width, and height of the .card element.
5. Calculate the relative distance as a value between -1 and 1 for the x and y axes and apply it through the transform property.

Here is the sample HTML and CSS code for the card:

<div class="container">
  <div class="shifting-card">
    <div class="content">
      <h3>Card</h3>
      <p>
        Lorem ipsum dolor sit amet consectetur adipisicing elit. Corrupti
        repellat, consequuntur doloribus voluptate esse iure?
      </p>
    </div>
  </div>
</div>

.container {
  display: flex;
  padding: 24px;
  justify-content: center;
  align-items: center;
  background: #f3f1fe;
  perspective: 1000px;
}

.shifting-card {
  width: 350px;
  display: flex;
  flex-direction: column;
  align-items: center;
  background: #fff;
  border-radius: 10px;
  margin: 0.5rem;
  transition: transform 0.2s ease-out;
  box-shadow: 0 0 5px -2px rgba(0, 0, 0, 0.1);
}

.shifting-card .content {
  text-align: center;
  margin: 2rem;
  line-height: 1.5;
  color: #101010;
}

And here is the JavaScript code to add the hover effect:

const card = document.querySelector(".shifting-card");
const { x, y, width, height } = card.getBoundingClientRect();
const cx = x + width / 2;
const cy = y + height / 2;

const handleMove = (e) => {
  const { pageX, pageY } = e;
  const dx = (cx - pageX) / (width / 2);
  const dy = (cy - pageY) / (height / 2);
  e.target.style.transform = `rotateX(${10 * dy * -1}deg) rotateY(${
    10 * dx
  }deg)`;
};

const handleOut = (e) => {
  e.target.style.transform = "initial";
};

card.addEventListener("mousemove", handleMove);
card.addEventListener("mouseout", handleOut);
