Let’s start by writing the HTML. This is the skeleton of our layout.

<!DOCTYPE html>
<html lang="en">
<head>
  <meta charset="UTF-8">
  <meta name="viewport" content="width=device-width, initial-scale=1.0">
  <title>Responsive Flexbox Cards</title>
  <link rel="stylesheet" href="styles.css">
</head>
<body>

  <div class="card-container">
    <div class="card">
      <h2>Card Title 1</h2>
      <p>This is a short description of the card content.</p>
    </div>
    <div class="card">
      <h2>Card Title 2</h2>
      <p>This is a short description of the card content.</p>
    </div>
    <div class="card">
      <h2>Card Title 3</h2>
      <p>This is a short description of the card content.</p>
    </div>
  </div>

</body>
</html>

🔍 Explanation:

.card-container is the outer box that holds all the cards.
Each .card is an individual box with a title and paragraph.

🎨 Step 2: Style the Layout with CSS

Now let’s make it look good using CSS Flexbox.

Create a file named styles.css and add the following styles:

/* Reset and base styles */
* {
  box-sizing: border-box;
  margin: 0;
  padding: 0;
  font-family: sans-serif;
  line-height: 1.5;
}

/* Container holds all cards */
.card-container {
  display: flex;            /* Enable Flexbox */
  flex-wrap: wrap;          /* Wrap to next line if space runs out */
  justify-content: center;  /* Center the cards */
  gap: 20px;                /* Space between cards */
  padding: 20px;
  background-color: #f8f9fa;
}

/* Each card box */
.card {
  background-color: white;
  width: 300px;
  padding: 20px;
  border-radius: 10px;
  box-shadow: 0 4px 10px rgba(0,0,0,0.1);
  transition: transform 0.3s ease;
}

.card:hover {
  transform: translateY(-5px); /* Lift effect on hover */
}

.card h2 {
  font-size: 1.5rem;
  margin-bottom: 10px;
  color: #333;
}

.card p {
  font-size: 1rem;
  color: #666;
}

🧠 Step-by-Step CSS Explanation

✅ `display: flex`

Turns the container into a Flexbox, which allows us to align cards horizontally.

✅ `flex-wrap: wrap`

If there’s not enough space in one row, the cards will move to the next line.

✅ `justify-content: center`

Centers the cards horizontally inside the container.

✅ `gap: 20px`

Adds space between the cards—cleaner than using margin manually.

✅ `.card`

Each card:

Has a fixed width (300px)
Padding inside the card
White background with subtle shadow
Rounded corners

✅ Hover effect

When you move your mouse over a card, it moves up slightly, making it feel interactive.

📱 Step 3: Make It Responsive

We want the cards to look great on mobile too. Let’s add a media query to stack them vertically.

Add this at the end of your CSS:

📝 What It Does:

When the screen size is 768px or smaller, each card stretches to fill the container’s width. Cards appear in a vertical stack, which is easier to read on phones.

🖼️ Bonus: Add Image to Cards
