NEW QUESTION # 22
A local photographer asks you to add filters as shown to the images in their photo gallery so that the images are not recognizable until authorized users log in.
Example of original and filtered images:
* Original image: full-color flower image
* Filtered image: blurred grayscale image
Analyze the images on the left.
Construct a CSS selector that will apply the appropriate filters to the images to meet the requirements.
Complete the markup by moving the appropriate HTML tags from the list on the left to the correct locations on the right. You may use each HTML tag once, more than once, or not at all.
Note: There is more than one correct markup. You will receive credit for any correct markup completion.
Answer:
Explanation:
Explanation:
First blank: img
Second blank: filter:
Third blank: grayscale(100%)
Fourth blank: blur(8px)
The correct CSS selector is img because the requirement applies the visual effect to gallery images. The correct property is filter:, not transform:, because CSS filters modify the rendered appearance of an element using image-processing effects such as blur, grayscale, opacity, brightness, contrast, and shadows. The filtered sample appears blurred and colorless, so the appropriate filter functions are grayscale(100%) and blur (8px). grayscale(100%) removes all color from the image, converting it to a black-and-white rendering. blur (8px) obscures visual details, making the image difficult to recognize until the protected or authorized state changes the styling. The filter keyword without a colon is not a valid CSS declaration in this context.
brightness(40%) and opacity(50%) could further obscure an image, but they are not required to reproduce the shown filtered result. The final declaration is therefore filter: grayscale(100%) blur(8px);.
NEW QUESTION # 23
You have created custom error messages for a form. When a user attempts to submit the form with invalid data, the following must occur:
* The data must remain in the form.
* Error messages must be displayed.
Which Event property or method should you use?
Answer: D
Explanation:
The correct method is preventDefault(). In an HTML form submission workflow, the browser's default action is to submit the form, which commonly navigates away from the current page or reloads it. Calling event.
preventDefault() inside the form's submit event handler cancels that default action, allowing the current form state to remain visible while custom validation logic displays error messages. MDN defines preventDefault() as the method that cancels the default action normally taken by the implementation for that event. The submit event is the correct event context because it fires when the form submission is triggered. defaultPrevented is only a Boolean property indicating whether cancellation has already occurred; it does not cancel anything.
cancelable only reports whether an event can be canceled. abort is not the correct form-validation event method. References/topics: HTML5 form validation, custom validation messages, submit event handling, event cancellation, preserving user input.
NEW QUESTION # 24
You need to use a flexbox so that new content you add to the container appears at the highest point on a vertical list. You want to achieve this goal without specifying an order. Which value should you use for flex- direction?
Answer: C
Explanation:
The correct value is column-reverse. The flex-direction property defines the main axis of a flex container and determines whether flex items are laid out horizontally, vertically, or in the reverse direction. column creates a vertical layout where items flow from the top of the container toward the bottom. If new content is appended after existing content, normal column layout places that new item later in the visual list, typically lower on the page. column-reverse preserves a vertical main axis but reverses the visual direction, so later items in the source order appear at the highest visual point of the list. This satisfies the requirement without using the order property on individual flex items. row and row-reverse are incorrect because they create horizontal layouts, not vertical lists. The reverse-direction flex values should be used deliberately because visual order can differ from DOM order, but for this exam scenario, column-reverse is the value that places newly appended vertical content at the top. References/topics: CSS flexbox, flex-direction, main axis, column layout, reverse visual flow.
NEW QUESTION # 25
Which two functions support 2D transformations in CSS3? Choose 2.
Answer: C,E
Explanation:
The correct 2D transformation functions are matrix() and skew(). CSS transformations are applied through the transform property, which accepts transform functions that can move, rotate, scale, skew, or otherwise alter an element visually in two-dimensional or three-dimensional space. MDN describes the < transform-function > type as representing transformations that affect an element's appearance and can operate in 2D or 3D space.
The matrix() function is valid because it defines a homogeneous two-dimensional transformation matrix, allowing multiple transform effects to be represented in a single function. The skew() function is also valid because it distorts an element along the 2D plane. move() is not a CSS transform function; the standard movement function is translate(). scroll() is not a transform function; scrolling is controlled through overflow and scroll APIs. zoom() is not a CSS3 2D transform function. References/topics: CSS3 transforms, transform property, 2D transformation functions, matrix(), skew().
NEW QUESTION # 26
Which JavaScript method is used to draw a circle on a canvas?
Answer: C
Explanation:
The correct method is arc(). In the Canvas 2D API, circles and circular arcs are drawn by creating an arc path on the canvas rendering context. MDN defines CanvasRenderingContext2D.arc() as creating a circular arc centered at (x, y) with a specified radius, start angle, end angle, and drawing direction. To draw a full circle, the common pattern is to call beginPath(), then arc(x, y, radius, 0, 2 * Math.PI), and then use stroke() or fill() to render the path. There is no standard Canvas 2D method named circle(), so option A is invalid. ellipse() can draw ellipses and can mathematically draw a circle if both radii are equal, but the classic and exam-targeted method for drawing a circle is arc(). bezierCurveTo() draws cubic Bezier curves and is used for custom curved paths, not the direct circle primitive. References/topics: Canvas 2D context, arc() method, drawing circles, radians, path rendering.
