Game Architecture and HTML Structure

Understand how the game works and write the HTML skeleton

🎓

This is your final project!

You've completed the JavaScript course and the HTML/CSS course. Now it's time to bring all your knowledge together and write a real game. Memory Game is a classic game with 16 cards (8 pairs), all face-down. You flip two — if they match, they stay open. If not — they flip back. Goal: reveal all pairs as fast as possible.

What we'll use

JavaScript:

Arrays — store cards
Functions — shuffle, flipCard, checkMatch
if/else — pair checking
Loops — render cards
DOM — document.createElement, classList
setInterval — timer

HTML:

Semantic structure (header, main)
divs for cards and grid
id and class attributes

CSS:

CSS Grid for the card grid
transition + transform for the flip animation
backface-visibility for the 3D effect

CSS для гри

Скопіюй цей CSS в файл style.css — він вже готовий, весь фокус буде на JavaScript:

css

* { box-sizing: border-box; margin: 0; padding: 0; }

body {
  min-height: 100vh;
  display: flex;
  align-items: center;
  justify-content: center;

  align-items: center;
  margin-bottom: 24px;
  flex-wrap: wrap;
  gap: 12px;
}

.game-header h1 { font-size: 1.5rem; color: #1e293b; }

.stats { display: flex; gap: 16px; }
.stat { text-align: center; }
.stat-label { font-size: 0.75rem; color: #64748b; display: block; }

.card {

.card-inner {

  height: 100%;
  position: relative;

  transition: transform 0.4s ease;
  border-radius: 10px;
}

.card.flipped .card-inner,
.card.matched .card-inner {
  transform: rotateY(180deg);
}

.card-front,
.card-back {
  position: absolute;
  width: 100%;
  height: 100%;
  border-radius: 10px;
  display: flex;
  align-items: center;
  justify-content: center;

  font-weight: 700;
}

.card-back {
  background: white;
  border: 2px solid #e2e8f0;
  transform: rotateY(180deg);
}

.card.matched .card-back { border-color: #22c55e; background: #f0fdf4; }
.card.matched { pointer-events: none; }

/* Екран перемоги */
.win-screen {
  position: fixed;

  margin-top: 8px;
}

You don't need to understand every CSS line right away! The key is you already know grid, flexbox, transition, backface-visibility from the course. Copy the CSS and focus on the JavaScript logic — that's what we'll write in the tasks.
