問題 #33
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.
答案：
解題說明：
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.
問題 #34
Review the markup segment. Which entry will validate successfully according to the required pattern?
答案：D
解題說明：
The valid entry is A, assuming the OCR-corrupted option represents the intended secret-code format: four letters, a hyphen, two digits, a hyphen, four digits, a hyphen, and four letters. The HTML pattern attribute defines a regular expression that an input value must satisfy during constraint validation. MDN specifies that pattern is used to define a regular expression the input value must match. In the intended pattern, the first group must contain exactly four alphabetic characters, the second group exactly two numeric digits, the third group exactly four numeric digits, and the final group exactly four alphabetic characters. Option A satisfies that structure: kukX is four letters, 04 is two digits, 4938 is four digits, and WJDF is four letters. Option B fails because the final group Uhj6 contains a digit. Option C fails because the first group includes a digit and the digit grouping/hyphen structure is wrong. Option D fails because 23h contains a letter where only digits are allowed. References/topics: HTML5 form validation, pattern attribute, regular-expression validation, text input constraints.
問題 #35
The ctx variable is the context of an HTML5 canvas object. What does the following HTML markup draw?
ctx.arc(x, y, r, 0, Math.PI, true);
答案：A
解題說明：
The statement draws a semicircle at the specified point. The arc() method of the Canvas 2D API adds a circular arc to the current path. Its core parameters are the center point x, y, the radius, the starting angle, the ending angle, and an optional direction flag. In this expression, x and y define the center of the arc, and r defines its radius. The start angle is 0 radians, and the end angle is Math.PI radians. Since Math.PI represents
180 degrees, the path covers exactly half of a full circle. The final argument, true, tells the canvas context to draw the arc counterclockwise rather than using the default clockwise direction; however, the angular span remains half of the circumference. The call does not draw a complete visible shape unless the path is later stroked or filled, but the geometric path being created is a semicircular arc. It is not a straight line, square, or full circle. References/topics: Canvas 2D context, arc() method, radians, path construction, drawing arcs and circles.
問題 #36
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.
答案：
解題說明：
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.
問題 #37
You are creating a form that requires the category to be entered as a two- or three-letter abbreviation. The input is mandatory.
You need to configure the input validation for the form.
Complete the markup by typing into the boxes.
Note: You will receive partial credit for each correct answer.
答案：
解題說明：
minlength , maxlength , required
Explanation:
First box: minlength
Second box: maxlength
Third box: required
The correct validation attributes are minlength, maxlength, and required. The input must accept a category abbreviation that is either two or three characters long. The minlength= " 2 " attribute enforces the lower boundary by preventing submission when the entered text contains fewer than two characters. The maxlength= " 3 " attribute enforces the upper boundary by preventing the user from entering more than three characters into the field. Since the question states that the input is mandatory, the required attribute must also be included. required is a Boolean validation attribute, so it does not need a value; its presence alone makes the field required before the form can be submitted. Together, these attributes configure basic HTML5 constraint validation directly in markup without requiring JavaScript. The completed input therefore requires a value, rejects values shorter than two characters, and limits the value to no more than three characters.
References/topics: HTML5 form validation, minlength, maxlength, required, text input constraints, mandatory form fields.
