A developer needs to create a user interface element that changes its border color when hovered over, while keeping the same border size and style. What combination of CSS properties should they use?
- border, border-hover, color-hover
- border, hover, color
- border-color, hover-color, border-style
- border-hover-color, border-hover-style, border-hover-width
To achieve the desired effect, the developer should use the border-color property along with the :hover pseudo-class. For example: border-color: initial; border-color: red; This ensures that only the color changes on hover while keeping the other border properties intact.

Setting align-items: baseline; aligns the items along their baselines within the flex container. This property is useful for aligning text or inline elements based on their text baseline.
What is the main visual difference between a box shadow applied with an inset keyword and one without it?
- box-shadow: 0 0 10px rgba(0, 0, 0, 0.5), inset 0 0 10px #888888;
- box-shadow: 0 0 10px rgba(0, 0, 0, 0.5);
- box-shadow: 5px 5px 10px #888888;
- box-shadow: inset 5px 5px 10px #888888;
The main visual difference between a box shadow with and without the inset keyword is the direction of the shadow. A regular box shadow appears outside the element, creating a shadow around it, while an inset box shadow appears inside the element, giving it a depressed or embossed look.

What is the difference between position: absolute; and position: fixed; in terms of the reference point for positioning?
- Relative to the initial containing block
- Relative to the nearest positioned ancestor

- Adaptive
- Fixed-width
