Breakdown of the Question

The question asks about the properties that contribute to the width of a box in CSS, specifically which elements are included in its measurement.

Relevant Concepts

In CSS box model, the width of a box is calculated based on the following properties:

1. Content: The actual content of the box.
2. Padding: The space between the content and the border.
3. Border: The border surrounding the padding.
4. Margin: The space outside the border.

However, in standard box model calculations, the margin is not included in the total width of the box. Instead, the total width can be defined as: $\text{Total Width} = \text{Content Width} + \text{Padding} + \text{Border}$

Analysis and Detail

1. Content: The width that the actual content occupies.
2. Padding: Adds space around the content, thus contributing to the overall width.
3. Border: The element that encloses the padding, further adding to the overall width.
4. Margin: While it affects the spacing between elements, it is not included in the box's width.

Verify and Summarize

From the analysis, the properties that contribute to the width of a box are indeed the content, padding, and border. Therefore, the correct answer to the question is that the width includes the content, padding, and border.

Final Answer

The correct answer is "Nội dung, padding, border và margin" (Content, padding, border, and margin).
