<body>Section:<h2>CodeCraft by Rana</h2>: Displays the title of the page on the screen.<button id="btn" class="magic">Magic 🎩</button>: A button with the text “Magic 🎩” and an IDbtn. This button is used to trigger the JavaScript functionality.<div id="boxes" class="boxes big"></div>: An empty container that will be populated with boxes using JavaScript. It has both anid="boxes"and a classboxes big.<script src="script.js"></script>: Links to the external JavaScript file (script.js), which controls the dynamic behavior of the page.

Explanation:
- Global Styles:
@importstatements import Google Fonts (Roboto and Poppins).* { box-sizing: border-box; }: Ensures that padding and borders are included in the element’s total width and height.
bodystyles: The body is centered, has a light background, and uses the Roboto font..magicbutton styles: A yellow button with white text, slightly rounded corners, and a shadow. When clicked or focused, it changes appearance with subtle animations..boxes: A container for the boxes. It has a fixed size of 500px by 500px, and when thebigclass is applied, it enlarges to 600px by 600px..boxstyles: Each box displays a section of a GIF, with a skewed shadow effect created using::afterand::beforepseudo-elements.
3. JavaScript Code
//CodeCraft by Rana
const boxesContainer = document.getElementById("boxes");
const btn = document.getElementById("btn");
btn.addEventListener("click", () => boxesContainer.classList.toggle("big"));
function createBoxes() {
for (let i = 0; i < 4; i++) {
for (let j = 0; j < 4; j++) {
const box = document.createElement("div");
box.classList.add("box");
box.style.backgroundPosition = `${-j * 125}px ${-i * 125}px`;
boxesContainer.appendChild(box);
}
}
}
createBoxes();
Explanation:
- DOM Element Selection:
const boxesContainer = document.getElementById("boxes");: Selects the<div>with theid="boxes".const btn = document.getElementById("btn");: Selects the<button>with theid="btn".
- Event Listener:
btn.addEventListener("click", () => boxesContainer.classList.toggle("big"));: The big class is toggled on the boxes Container when the button is clicked. This triggers the CSS transformation that enlarges the box grid and rotates each box.
- createBoxes Function:
createBoxes(): This function dynamically creates 16divelements (4 rows and 4 columns) and adds theboxclass to each of them.- The
backgroundPositionproperty is set based on the row (i) and column (j), ensuring each box displays a different part of the background image. - Finally, the box is appended to the
boxesContainer.
- Function Call:
createBoxes();: Immediately calls thecreateBoxes()function to create the boxes when the page loads.
Overall Summary:
This code creates a grid of 16 boxes (4x4), each displaying a portion of a large GIF. The button, labelled "Magic 🎩", triggers a transformation on the grid, enlarging it and rotating the boxes in 3D. The dynamic behavior is handled with JavaScript, while the styling is done through CSS. read more
