NEW QUESTION # 46
You need to complete a postal code input form element (post_code). Include attributes to make the field mandatory, set the data type as text, and limit the input to five numeric digits.
Complete the code by selecting the correct option from each drop-down list.
Note: You will receive partial credit for each correct selection.
Answer:
Explanation:
Explanation:
First blank: type
Second blank: pattern
Third blank: required
The first blank must be type because the question requires the input data type to be text, producing type= " text " . The second blank must be pattern because [0-9]{5} is a regular expression that permits exactly five numeric digits. The third blank must be required because the postal code field must be mandatory before the form can be submitted.
NEW QUESTION # 47
You need to draw a blue rectangle that meets these conditions:
* It is 200 by 200 pixels.
* It contains a white circle that is centered within the rectangle.
* The circle has a 50-pixel radius.
* The image should appear as follows: a blue square with a centered white circle.
Refer to the image on the left.
You need to ensure that the image scales without distortion when the page is resized. You must not be required to use JavaScript.
Complete the code by selecting the correct option from each drop-down list.
Note: You will receive partial credit for each correct selection.
Answer:
Explanation:
Explanation:
First blank: < svg width= " 200 " height= " 200 " >
Second blank: < rect width= " 200 " height= " 200 "
Third blank: < circle cx= " 100 " cy= " 100 " r= " 50 "
Fourth blank: < /svg >
The correct solution uses SVG because SVG graphics are vector-based and can scale without pixel distortion when the page or viewport changes. A < canvas > element would require script-based drawing logic, which violates the requirement that JavaScript must not be required. An < img > or < picture > element can display an image, but those options do not define the rectangle and circle directly in markup. The outer container must therefore be < svg width= " 200 " height= " 200 " > . The blue square is created with < rect width= " 200 " height= " 200 " fill= " blue " / > , which produces a rectangle matching the required 200-by-200 dimensions.
The centered white circle must use SVG circle geometry: cx= " 100 " and cy= " 100 " place the center at the midpoint of the 200-by-200 square, and r= " 50 " creates the required 50-pixel radius. The final closing tag must be < /svg > .
NEW QUESTION # 48
You need to identify the form elements.
Move the appropriate semantic elements from the list on the left to the correct locations on the right.
Note: You will receive partial credit for each correct response.
Answer:
Explanation:
Explanation:
Club Points indicator # < meter >
Order Status group title # < legend >
Choose delivery frequency options # < datalist >
Shipping Information group box # < fieldset >
Displayed shipping information # < output >
The correct semantic elements are selected according to the role each visible form component performs. The Club Points visual indicator represents a scalar measurement within a known range, so it corresponds to < meter > . The bordered Order Status section is a grouped form region, and the caption displayed on the border is a < legend > , which labels a fieldset-style group. The delivery frequency control shows an editable input with selectable predefined values, which is the purpose of < datalist > : it supplies suggested options for an associated input without forcing the user to choose only from the list. The Shipping Information section is visually and semantically a grouped set of related form information, so the surrounding grouping element is < fieldset > . The displayed shipping address is generated or presented as result-style information rather than typed directly in that location, which matches < output > . fieldset groups related controls, legend labels that group, meter displays a bounded measurement, datalist provides input suggestions, and output displays calculated or resulting information.
NEW QUESTION # 49
Which two statements correctly describe media queries? Choose 2.
Answer: C,D
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

NEW QUESTION # 50
Which CSS property defines the sides of an element where other floating elements are not allowed?
Answer: D
Explanation:
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.
