The correct answer is D. all of the mentioned.
A dashed outline is an outline that is made up of dashes. The dashes can be of any length, but they must be evenly spaced. The most common type of dashed outline is a double-dash outline, which is made up of two dashes that are separated by a space.
The following CSS property can be used to specify a dashed outline:
outline: dashed;
The outline property takes a list of values, each of which specifies a different type of outline. The first value in the list is the type of outline, which can be one of the following:
none: No outline.solid: A solid outline.dashed: A dashed outline.dotted: A dotted outline.double: A double outline.groove: A groove outline.ridge: A ridge outline.inset: An inset outline.outset: An outset outline.
The remaining values in the list specify the properties of the outline, such as the color, width, and dash length.
For example, the following CSS code specifies a dashed outline with a width of 2px and a dash length of 4px:
outline: dashed 2px 4px;
