Review the images on the left.
Complete the statements by selecting the correct option from each drop-down list.
Note: You will receive partial credit for each correct selection.

Explanation:
First drop-down: flex boxes
Second drop-down: background-size
Third drop-down: cover
The correct layout mechanism is responsive flex boxes because the content changes from a vertical mobile arrangement to a wider multi-column layout as space becomes available. Flexbox supports this behavior naturally through flexible item sizing and wrapping, often without needing explicit media queries for every screen size. The header image must fill its visible header region on both mobile and desktop. The correct CSS property for controlling how a background image scales inside its container is background-size. The correct value is cover, because background-size: cover scales the image so that the entire container is covered while preserving the image's aspect ratio. This prevents distortion, although some cropping can occur when the image and container have different aspect ratios. contain would preserve the full image but may leave empty space. auto would use the image's intrinsic size and would not reliably fill the header area. background- attachment, background-clip, and background-repeat do not control image scaling.

You need to display the following user interface:
A text input field that displays a selectable suggestion list containing:
Motorcycle
Truck
Boat
Car
Bicycle

Explanation:

The correct markup uses the HTML5 < datalist > element because the interface shows a text input with a drop- down list of suggested values. The < input > element has list= " vehicles " , which means it must be connected to a < datalist > whose id value is exactly vehicles. This relationship is essential: the list attribute on the input references the id of the datalist that supplies the available options. Each < option > element inside the datalist defines one suggested value: Motorcycle, Truck, Boat, Car, and Bicycle. Unlike a traditional < select > element, a datalist does not restrict the user only to the listed choices; the user can either select an option with the mouse or type directly into the input field. That behavior matches the displayed interface, where the control appears as an editable text box with suggestions. The final closing tag must be < /datalist > because the option elements belong to the datalist container. References/topics: HTML5 forms, < input list > , < datalist > , option elements, selectable typed input.

You need to correctly apply a style rule for screen devices with a width of 480 pixels or less.
Complete the code by selecting the correct option from the drop-down list.

Explanation:
@media screen and (max-width: 480px) {
/* style rules go here */
}
The correct media query is @media screen and (max-width: 480px) {. The requirement says the style rule must apply to screen devices with a width of 480 pixels or less. In CSS media queries, screen identifies the media type, and (max-width: 480px) defines the upper viewport-width limit. This means the enclosed CSS rules apply when the viewport is 480 pixels wide or any smaller value, which is the standard mobile breakpoint behavior. @media screen and (width: 480px) is incorrect because it applies only when the viewport is exactly 480 pixels wide, not below it. @media screen display and (width: 480px) is invalid syntax because display is not used that way in a media query. @media screen-width: 480px is also invalid because it does not follow the required @media media-type and (feature: value) pattern.
