        <div class="card border-0 shadow-sm">
            <div class="card-body">
                <!-- Your stat content -->
            </div>
        </div>

## 💡 Best Practices

### Consistent Spacing
- Use Bootstrap spacing utilities (`mb-3`, `mt-4`, `p-3`)
- Keep card padding consistent (`p-4` or `p-3`)
- Use gap utilities for flex layouts (`gap-2`, `gap-3`)

### Consistent Button Styles
```html
<button class="btn btn-primary">Primary Action</button>
<button class="btn btn-outline-secondary">Secondary Action</button>
<button class="btn btn-sm btn-outline-primary">Small Button</button>
```

### Consistent Card Headers
```html
<div class="card-header bg-white border-0 py-3">
    <h5 class="mb-0 fw-semibold">Title</h5>
</div>
```

### Use Icons Consistently
Always pair icons with text using `me-2` (margin-end):
```html
<i class="bi bi-plus-circle me-2"></i>Add New
```

## 🎨 Example: Creating a Jobs Page

```html
@model List<JobListDto>
@{
    ViewData["Title"] = "Jobs";
}

<!-- Stats Cards -->
<div class="row g-3 mb-4">
    <div class="col-md-3">
        <div class="card border-0 shadow-sm">
            <div class="card-body">
                <div class="d-flex justify-content-between align-items-center">
                    <div>
                        <p class="text-muted mb-1" style="font-size: 0.875rem;">Active Jobs</p>
                        <h3 class="mb-0 fw-bold">@Model.Count(j => j.Status != JobStatus.Completed)</h3>
                    </div>
                    <div class="rounded-circle p-3" style="background: #dbeafe;">
                        <i class="bi bi-briefcase text-primary" style="font-size: 1.5rem;"></i>
                    </div>
                </div>
            </div>
        </div>
    </div>
    <!-- Add more stat cards -->
</div>
