CSS (Cascading Style Sheets) is the stylesheet language used to control the presentation of HTML documents. It manages layout, colors, typography, and responsive design.

⚡ Key Features

Selectors and rules to target HTML elements
Layouts with Flexbox and Grid
Responsive design using media queries
Styling with colors, fonts, spacing, and animations
Cascading order and inheritance for consistent design
Supports custom properties and modular patterns

⚠️ Considerations

Cascade and specificity can be confusing at first
Cross-browser compatibility requires testing
Large stylesheets can become hard to maintain
Needs good organization for scalable projects

💻 Example

button {
  background: #4a90e2;
  color: white;
  padding: 12px 20px;
  border-radius: 6px;
}

🎨 CSS Core Layers
