Question

what elements can you add to your css styling sheet

Answer 1

In a CSS (Cascading Style Sheets) styling sheet, you can add various elements to control the layout and appearance of HTML documents. Here’s a list of common elements and features you can include in your CSS:

### Basic Selectors
1. **Type selectors**: Target HTML elements by their type (e.g., `h1`, `p`, `div`).
2. **Class selectors**: Target elements with specific classes using a dot (e.g., `.class-name`).
3. **ID selectors**: Target elements with specific IDs using a hash (e.g., `#id-name`).
4. **Universal selector**: Targets all elements using `*`.
5. **Attribute selectors**: Target elements with specific attributes (e.g., `[type="text"]`).

### Combinators
1. **Descendant selector**: Selects an element that is a descendant of another (e.g., `div p`).
2. **Child selector**: Selects an element that is a direct child of another (e.g., `div > p`).
3. **Adjacent sibling selector**: Selects an element that is directly after another (e.g., `h1 + p`).
4. **General sibling selector**: Selects all siblings after a specified element (e.g., `h1 ~ p`).

### Pseudo-classes
- Target elements in a specific state (e.g., `:hover`, `:active`, `:focus`, `:nth-child(n)`).

### Pseudo-elements
- Style specific parts of an element (e.g., `::before`, `::after`, `::first-line`, `::first-letter`).

### Media Queries
- Use media queries to apply styles based on the device characteristics (e.g., screen size).
```css
@media (max-width: 600px) {
body {
background-color: lightblue;
}
}
```

### Variables and Functions
- **CSS Variables (Custom Properties)**: e.g., `--main-color`.
