질문 # 50
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 # 51
Which two statements correctly describe media queries? Choose 2.
정답：B,D
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 # 52
Which CSS property defines the sides of an element where other floating elements are not allowed?
정답：D
설명：
The correct property is clear. In CSS layout, float removes an element from the normal inline flow and positions it to the left or right, allowing following content to wrap beside it. The clear property controls whether an element may be positioned next to preceding floated elements or must be moved below them.
MDN defines clear as the property that sets whether an element must be moved below floating elements that precede it. Typical values include left, right, both, and none, allowing the developer to block floats on one or both sides. display controls the formatting behavior of an element, such as block, inline, flex, or grid. float creates the floating behavior; it does not prevent other floats from appearing beside an element. position controls positioning schemes such as static, relative, absolute, fixed, or sticky. Therefore, only clear directly defines the sides where adjacent floating elements are not permitted. References/topics: CSS floats, content flow, clearing floated elements, layout positioning.
질문 # 53
Which markup segment creates an SVG ellipse?
정답：B
설명：
The correct answer is D because an SVG ellipse is created with the < ellipse > element and the required geometry attributes cx, cy, rx, and ry. The cx attribute defines the x-coordinate of the ellipse's center point, and cy defines the y-coordinate of the center point. The rx attribute defines the horizontal radius, while ry defines the vertical radius. In option D, cx= " 200 " and cy= " 80 " correctly position the center of the ellipse, while rx= " 100 " and ry= " 50 " correctly define an ellipse that is wider than it is tall. Option A is invalid because the element name is misspelled as < ellipsp > , so the browser will not interpret it as an SVG ellipse.
Option B incorrectly uses x and y attributes instead of the ellipse-specific center and radius attributes. Option C correctly uses cx and cy, but incorrectly uses x and y where rx and ry are required. References/topics: SVG markup, < svg > container, < ellipse > element, center coordinates, horizontal radius, vertical radius.
질문 # 54
Which two functions support 2D transformations in CSS3? Choose 2.
정답：C,D
설명：
The correct transformation functions are matrix() and skew(). CSS transformations are applied with the transform property and accept transform functions that alter an element's rendered appearance in two- dimensional or three-dimensional space. MDN defines < transform-function > as a data type representing a transformation that can rotate, resize, distort, or move an element in 2D or 3D space. The matrix() function is valid because it defines a homogeneous two-dimensional transformation matrix, allowing translation, scaling, rotation, and skewing effects to be represented numerically in one function. The skew() function is also valid because it explicitly skews an element on the 2D plane. scroll() is not a CSS transform function; scrolling is handled through overflow behavior or scrolling APIs. move() is also not a valid CSS transform function; the standard transform function for movement is translate(). References/topics: CSS3 transforms, transform property, 2D transformation functions, matrix(), skew().
