App.css

Add the following CSS to make the app wider and style it properly:

.App {
  max-width: 1200px;
  margin: 0 auto;
  padding: 20px;
  font-family: Arial, sans-serif;
}

.title-section {
  text-align: center;
  margin-bottom: 30px;
}

.title-section h1 {
  font-size: 2.5rem;
  margin-bottom: 10px;
}

.title-section p {
  font-size: 1.2rem;
  color: #666;
}

.button-section {
  text-align: right;
  margin-bottom: 20px;
}

.dialog-content {
  display: flex;
  flex-direction: column;
  gap: 15px;
}

.grid-section {
  margin-top: 20px;
}

.progress-section {
  margin-top: 30px;
}

.k-card {
  box-shadow: 0 4px 8px rgba(0, 0, 0, 0.1);
  border-radius: 8px;
}

.k-card-title {
  font-size: 1.5rem;
  font-weight: bold;
}

.k-card-body {
  padding: 20px;
}

Key Changes

1. Wider Layout: The app now has a max-width of 1200px and is centered on the page.
2. Title Section: Added a title and subtitle at the top of the app.
3. Improved Styling: Added padding, margins, and shadows to make the app more visually appealing.
4. Full-Width Components: Adjusted the width of inputs, dropdowns, and the grid to take up the full available space.

How It Looks

1. Title Section: A centered title and subtitle at the top.
2. Add Task Button: Positioned at the top-right corner.
3. Dialog: A modal form for adding new tasks.
4. Grid: Displays all tasks in a wide, responsive table.
5. Progress Bar: Shows the percentage of completed tasks in a card.
