Understanding HTML Closing Tags

In HTML, most elements require both an opening and a closing tag. However, there are specific cases where a valid HTML element does not need a closing tag.

1. Self-Closing Tags: Elements like <img>, <br>, and <input> are self-closing tags, meaning they don't have a closing counterpart. For example, <img src="image.jpg" alt="My Image"> is valid without a closing tag.

2. Optional Closing Tags: HTML allows for some flexibility where closing tags can be omitted for elements like <li>, <p>, and <dt>, if they are immediately followed by another element of the same type.

The correct answer to your question is: If It's a self-closing tag.
