NEW QUESTION # 29
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.

NEW QUESTION # 30
You need to display the following user interface:
A text input field that displays a selectable suggestion list containing:
Motorcycle
Truck
Boat
Car
Bicycle
Answer:
Explanation:
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.
NEW QUESTION # 31
Which two statements correctly describe media queries? Choose 2.
Answer: B,C
Explanation:
Media queries support responsive web design and allow different CSS rules to be applied at different screen sizes, device characteristics, or breakpoints. MDN describes media queries as a CSS mechanism for applying styles depending on media type and device or viewport characteristics, including width, height, resolution, and orientation. This is the foundation of responsive design because a page can adapt its layout for phones, tablets, laptops, and desktop displays without changing the HTML document. Breakpoints are the points where the design changes; MDN identifies them as the points where a media query is introduced to improve layout behavior across viewport sizes. Statement A is not generally correct because media queries are primarily a styling and layout mechanism, not a direct performance optimization. They can sometimes help avoid unsuitable layouts, but performance improvement is not their defining purpose. Statement D is incorrect because media queries are CSS rules; they do not execute or dynamically process JavaScript code. References
/topics: responsive design, CSS media queries, viewport width, breakpoints, adaptive layout rules.
NEW QUESTION # 32
Which code segment correctly displays images with 80% transparency and a blue 8px shadow?
Answer: A
Explanation:
The correct segment is D: filter: opacity(20%) drop-shadow(8px 8px blue);. The requirement says the image must have 80% transparency, which means only 20% opacity remains visible. The CSS filter property applies graphical effects to rendered elements, including image effects such as opacity adjustment and drop shadows.
The opacity() filter function is valid inside filter, and values below 100% make the rendered element more transparent. The drop-shadow() function is also a valid CSS filter function and applies a shadow effect to the input image. Option A changes saturation, not transparency. Option B also changes saturation and incorrectly attempts to use box-shadow() as a filter function. Option C uses opacity(80%), which would produce 80% opacity rather than 80% transparency, and it also uses invalid box-shadow() syntax inside filter. References
/topics: CSS filter property, opacity(), drop-shadow(), image effects, transparency.
NEW QUESTION # 33
You need to contain overflowing text inside the element ' s border without creating unneeded scrollbars or losing text. Which attribute setting should you use?
Answer: B
Explanation:
The correct setting is overflow: auto;. The requirement is precise: the text must remain inside the element's border, must not be lost, and scrollbars should not appear unless they are needed. overflow: auto satisfies all three requirements because it clips overflowing content to the element's box and creates scrollbars only when the content actually exceeds the available space. This preserves access to all text while avoiding unnecessary horizontal or vertical scrollbars when the content fits. overflow: hidden is incorrect because it clips the overflowing text and provides no scrolling mechanism, meaning some content may become inaccessible.
overflow: visible is incorrect because the extra text can flow outside the element boundary, violating the requirement to keep content inside the border. overflow: scroll is close but not optimal because it forces scrollbars even when they are not required, which directly conflicts with the instruction to avoid unneeded scrollbars. References/topics: CSS overflow, scroll containers, text containment, content clipping, layout flow.
