Final Answer:
Step-by-step explanation:
In the provided CSS code, the selector .selector is targeted. The display: inline-block; property is used to make the element behave as an inline block, allowing other elements to sit beside it horizontally. The width: 120px; property sets the width of the element to 120 pixels. These two CSS rules combined ensure that the targeted element with the class .selector becomes an inline-block element with a specific width of 120 pixels.
The display property controls the layout behavior of an element. By setting it to inline-block, the element retains its inline characteristics, allowing it to flow with surrounding content, while also gaining block-level properties, such as the ability to set a specific width.
The width property then determines the horizontal size of the element. In this case, it is set to 120 pixels, fulfilling the requirement for the inline-block element's width. This concise CSS code achieves the desired styling for the specified element without the need for additional complexity.
