How much horizontal space ("width") will this div use? div{ width: 50px; padding: 10px; margin: 5px; border: 2px; }

To determine the total horizontal space or width that the div will use, it's important to consider the box model, which includes the width of the content, padding, border, and margin.

1. The specified width of the div is 50 pixels.

2. Padding is the space inside the border and adds to the total width. In this case, there is 10 pixels of padding on each side (left and right), contributing a total of 20 pixels (10px + 10px).

3. The border adds thickness to the total width as well. Here, the border is specified as 2 pixels on each side, contributing an additional 4 pixels (2px + 2px).

4. The margin does not affect the calculated width of the div itself, but it does occupy additional space around the div. However, the question asks for the width utilized by the div, which generally excludes the margin when calculating internal width.

Now, calculate the total width:

• Width: 50px (content width)

• Padding: 20px (10px on left + 10px on right)

• Border: 4px (2px on left + 2px on right)

Now, adding these together:

50px
