Main and Cross Axes in Flexbox



Here are five simple examples illustrating the main and cross axes in Flexbox:

### 1. Horizontal Main Axis

```html
<!DOCTYPE html>
<html lang="en">
<head>
  <meta charset="UTF-8">
  <meta name="viewport" content="width=device-width, initial-scale=1.0">
  <title>Horizontal Main Axis</title>
  <style>
    .container {
      display: flex; /* Create a flex container */
      border: 2px solid #333;
      justify-content: space-around; /* Align items along the main axis */
    }
    .item {
      background-color: #f0f0f0;
      padding: 10px;
      margin: 5px;
    }
  </style>
</head>
<body>
  <div class="container">
    <div class="item">Item 1</div>
    <div class="item">Item 2</div>
    <div class="item">Item 3</div>
  </div>
</body>
</html>
```

### 2. Vertical Main Axis

```html
<div class="container" style="flex-direction: column; align-items: center;">
  <div class="item">Item 1</div>
  <div class="item">Item 2</div>
  <div class="item">Item 3</div>
</div>
```

### 3. Horizontal Cross Axis

```html
<div class="container" style="align-items: flex-end;">
  <div class="item">Item 1</div>
  <div class="item">Item 2</div>
  <div class="item">Item 3</div>
</div>
```

### 4. Vertical Cross Axis

```html
<div class="container" style="flex-direction: column; justify-content: flex-end;">
  <div class="item">Item 1</div>
  <div class="item">Item 2</div>
  <div class="item">Item 3</div>
</div>
```

### 5. Reversed Axes

```html
<div class="container" style="flex-direction: column-reverse; align-items: flex-end;">
  <div class="item">Item 1</div>
  <div class="item">Item 2</div>
  <div class="item">Item 3</div>
</div>
```

These examples demonstrate different configurations of flex containers and items to control alignment along the main and cross axes. Experiment with the `justify-content` and `align-items` properties to see how they affect the layout!
