What is the difference between block and inline elements?
Explanation:
Block and inline elements are two fundamental types of elements in HTML. Block elements take up the full width available and always start on a new line, whereas inline elements take up only as much width as necessary and do not start on a new line. Understanding the difference helps in controlling the layout and appearance of a webpage.
Key Talking Points:
- Block Elements:
- Occupy the full width of their parent container.
- Always start on a new line.
- Can contain other block and inline elements.
- Inline Elements:
- Occupy only the width required by their content.
- Do not start on a new line.
- Can only contain text or other inline elements.
NOTES:
Reference Table:
| Feature | Block Element | Inline Element |
|---|---|---|
| Width | Takes full width of the parent | Takes only as much width as needed |
| Line Break | Starts on a new line | Does not start on a new line |
| Containable Items | Can contain block and inline elements | Can contain only inline elements |
| Examples | <div>, <p>, <h1> | <span>, <a>, <strong> |

Question: Can you provide an example where using block elements would be more appropriate than inline elements?
