Which of the following property specifies the size of the mask?

The correct answer is: D. none of the mentioned

• box-sizing is a CSS property that specifies how the width and height of an element are calculated. It can have the values border-box, content-box, or padding-box.
• box-shadow is a CSS property that creates a shadow effect around an element. It takes four values: horizontal offset, vertical offset, blur radius, and color.
• box-reflect is a CSS property that creates a reflection effect on an element. It takes two values: x-offset and y-offset.

None of these properties specify the size of the mask. The size of the mask is specified by the mask-size property. The mask-size property takes two values: width and height. The width and height of the mask must be the same as the width and height of the element that it is applied to.

For example, the following CSS code will create a mask that is 100px wide and 100px high:

css
.mask {
width: 100px;
height: 100px;
}
