NEW QUESTION # 53
The following two images show a web page that uses a responsive layout displayed on a mobile device and on a PC.
Displayed on a mobile device:
The layout stacks the content vertically.
Displayed on a computer monitor:
The layout displays the content cards horizontally in multiple columns.
Review the images on the left.
Complete the statements by selecting the correct option from each drop-down list.
Answer:
Explanation:
Explanation:
First drop-down: flex boxes
Second drop-down: background-size
Third drop-down: cover
The layout changes from a stacked mobile layout to a multi-column desktop layout without relying on media queries. That behavior is commonly achieved with responsive flex boxes, where items can wrap naturally based on the available width. The header image must fill the available header area on both mobile and desktop. For that requirement, the correct CSS property is background-size, and the correct value is cover.
background-size: cover scales the image so the entire header area is filled, even if part of the image is cropped. contain would preserve the full image but could leave empty space, and auto would keep the image at its natural size.
NEW QUESTION # 54
You need to implement media queries for the responsive layout of a new website.
Low-resolution wireframes for the desktop, tablet, and mobile layouts are shown.
Answer:
Explanation:
Explanation:
Responsive layouts use CSS media queries to apply different style rules according to the viewport width or device characteristics. In this scenario, the three wireframes represent desktop, tablet, and mobile breakpoints.
The desktop layout should use @media only screen and (min-width: 1025px) because desktop screens are the widest target group and begin above the tablet maximum width. The tablet layout should use @media only screen and (min-width: 481px) and (max-width: 1024px) because it covers the middle range between mobile and desktop. The mobile layout should use @media only screen and (min-width: 285px) and (max-width:
480px) because it targets the smallest viewport range shown in the available choices. The option @media only screen and (max-width: 1025px) and (min-width: 1920px) is logically invalid because a viewport cannot simultaneously be at least 1920 pixels wide and no more than 1025 pixels wide. References/topics: responsive web design, CSS media queries, viewport breakpoints, mobile layout, tablet layout, desktop layout.
NEW QUESTION # 55
You need to complete the code for a registration form that must meet the following criteria:
* The Password must be 6-8 characters long and use only letters and numbers.
* The Member ID must follow the pattern ###-##-###.
Complete the markup by selecting the correct option from each drop-down list.
Note: You will receive partial credit for each correct selection.
Answer:
Explanation:
Explanation:
First drop-down: maxlength=8
Second drop-down: pattern=[A-Za-z0-9]{6,8}
Third drop-down: pattern=[0-9]{3}-[0-9] {2}-[0-9]{3}
The password field needs two constraints. maxlength=8 limits the user to a maximum of eight characters, satisfying the upper length requirement. The pattern=[A-Za-z0-9]{6,8} attribute enforces the complete password rule: only uppercase letters, lowercase letters, and digits are allowed, and the total length must be between six and eight characters. A pattern without {6,8} would not enforce the minimum length, and {1,8} would incorrectly allow passwords shorter than six characters. The Member ID field must follow the visible placeholder format 123-45-678, which is three digits, a hyphen, two digits, another hyphen, and three digits.
Therefore, the correct member ID pattern is pattern=[0-9] {3}-[0-9]{2}-[0-9] {3}. The hyphens must be included literally in the pattern because the required format contains them. max=8 is not appropriate for password text length, and size=8 only controls display width, not validation.
NEW QUESTION # 56
You need to complete a postal code input form element (post_code). Include attributes to make the field mandatory, set the data type as text, and limit the input to five numeric digits.
Complete the code by selecting the correct option from each drop-down list.
Note: You will receive partial credit for each correct selection.
Answer:
Explanation:
Explanation:
First blank: type
Second blank: pattern
Third blank: required
The first blank must be type because the question requires the input data type to be text, producing type= " text " . The second blank must be pattern because [0-9]{5} is a regular expression that permits exactly five numeric digits. The third blank must be required because the postal code field must be mandatory before the form can be submitted.
NEW QUESTION # 57
Identify the filter applied to each image.
Complete the markup by selecting the correct option from each drop-down list.
Note: You will receive partial credit for each correct selection.
Answer:
Explanation:
Explanation:
The first image has a brown/yellow vintage tone, which indicates the sepia(100%) CSS filter. Sepia converts the image colors into a warm monochrome effect commonly associated with aged photographs. The second image appears faded and washed out while retaining the same general image content, which corresponds to opacity(30%); this makes the image mostly transparent, allowing only 30 percent opacity. The third image shows the original beach image with a visible shadow offset behind it, so the correct filter is drop-shadow(8px
8px 10px black). The first two 8px values define the horizontal and vertical shadow offset, 10px defines the blur radius, and black defines the shadow color. saturate(100%) would leave saturation at its normal level and would not visibly create a special effect. grayscale(100%) would remove color entirely and produce a black- and-white image, which is not shown in the visible rows. References/topics: CSS filter property, image effects, sepia(), opacity(), drop-shadow(), graphical enhancement with CSS.
