질문 # 41
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.
정답：
설명：
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.

질문 # 42
Which two statements correctly describe media queries? Choose 2.
정답：A,C
설명：
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

질문 # 43
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.
정답：
설명：
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.
질문 # 44
Which value does the following JavaScript code fragment store in the variable num?
var num = localStorage.length;
정답：D
설명：
The value stored in num is the number of key-value pairs currently stored in localStorage. The localStorage object implements the Web Storage Storage interface, which stores data as named string key/value entries for the current origin. Its length property is read-only and returns the number of data items stored in that Storage object, not the size of the stored data and not the remaining capacity. MDN's Storage reference explicitly defines length as returning the number of data items stored, and its example shows that after three items are added to localStorage, localStorage.length returns 3. Therefore, if the storage area contains five named entries, num receives 5; if it contains no entries, num receives 0. Option A is incorrect because available bytes are not exposed through length. Option B is unrelated to Web Storage. Option C is incorrect because browser storage quota or capacity is separate from the length property.

질문 # 45
Move the appropriate attributes from the list on the left to the correct descriptions on the right. You may use each attribute once, more than once, or not at all.
Note: You will receive partial credit for each correct match.
정답：
설명：
Explanation:
pattern # Provides a way to set a regular expression that the value must match placeholder # Provides a way to set default text that displays until focus is placed in an element required # Provides a way to set form elements as mandatory multiple # Provides a way to allow more than one file or email address in a single input The correct matches are based on standard HTML5 form validation and input-attribute behavior. The pattern attribute defines a regular expression that the input value must satisfy before the form can be submitted successfully. It is commonly used for structured values such as phone numbers, codes, postal formats, or custom identifiers. The placeholder attribute supplies short hint text inside an input field, helping the user understand the expected value before entering data. The required attribute makes a form control mandatory; if the field is empty, constraint validation prevents successful submission. The multiple attribute allows a single input to accept more than one value, specifically for controls such as input type= " file " and input type= " email " , where users may upload multiple files or enter multiple email addresses. The maxlength attribute is not used in these matches because it limits the maximum number of characters that can be entered, but none of the listed descriptions asks for character-length restriction.
