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

To determine the total vertical space that the div will use, it is essential to consider several CSS properties that contribute to the box model, namely height, padding, margin, and border.

Initially, the div has a specified height of 50 pixels. Next, we add the padding, which is given as 5 pixels for the top and bottom (since the padding values are stated as "5px 10px", this means 5 pixels for the top and bottom, and 10 pixels for the left and right). Therefore, the total padding applied to the vertical space is:

• Top padding: 5px

• Bottom padding: 5px

That totals to 10 pixels of padding added to the height.

Next, we consider the border, which is stated as "2px". A border of 2 pixels applies to both the top and bottom of the div:

• Top border: 2px

• Bottom border: 2px

This adds another 4 pixels to the overall height.

Additionally, the margin of 5 pixels applies to both the top and bottom as well:

• Top margin: 5px

• Bottom margin: 5px

Again, this adds another 10 pixels to the overall
