An element will be positioned relative to the viewport if its position property is set to ________.

You have a complex web page layout with nested elements. You want to specifically style an element that is the second child of its parent, regardless of the type of element. Which pseudo-class selector will ensure your style is applied correctly?

- :nth-element(2)
- :second-child
The correct selector is :nth-child(2). This targets the second child element of its parent, irrespective of the element type. :second-child and :child(2) are not valid selectors, and :nth-element(2) is not a standard selector in CSS.

When trying to create a tooltip widget that appears above an element when hovered, which property and value pair is crucial to ensure that the tooltip does not affect the layout of surrounding elements when it is positioned?
- position: absolute, z-index: 1;
- display: none;
- visibility: hidden;
- opacity: 0;
The crucial property-value pair is position: absolute, z-index: 1;. This positions the tooltip absolutely, and the z-index ensures it appears above other elements. The other options either hide the tooltip completely or affect the layout of surrounding elements.
