NEW QUESTION # 59
Review the following markup segment:
< form action= " process.js " method= " get " >
< label for= " secretcode " > Secret Code < /label >
< input type= " text " name= " secretcode "
pattern= " [a-zA-Z]{4}-[0-9] {2}-[0-9]{4}-[a-zA-Z] {4} "
placeholder= " secretcode " >
< input type= " submit " value= " Submit " >
< /form >
Which entry will validate successfully according to the required pattern?
Answer: B
Explanation:
The correct answer is D because the pattern attribute requires the exact structure defined by the regular expression [a-zA-Z]{4}-[0-9] {2}-[0-9]{4}-[a-zA-Z] {4}. The first group, [a-zA-Z]{4}, requires exactly four alphabetic characters. The second group, [0-9] {2}, requires exactly two numeric digits. The third group, [0-9]
{4}, requires exactly four numeric digits. The final group, [a-zA-Z] {4}, requires exactly four alphabetic characters. Hyphens must appear between each group. Option D, kukX-34-4938-WJDF, satisfies every part:
kukX is four letters, 34 is two digits, 4938 is four digits, and WJDF is four letters. Option A fails because Uhj6 contains a digit in the final letter-only group. Option B fails because y7Ts contains a digit in the first group and A3 is not two digits. Option C fails because 23h contains a letter and breaks the two-digit group.

NEW QUESTION # 60
The following code adds items to the groceries array from the other arrays. Line numbers are for reference only.
01 < body >
02 < p id= " list " > < /p >
03 < script >
04 var groceries = [];
05 var dairy = [ " Milk " , " Eggs " , " Cheese " , " Ice Cream " ];
06 var beverages = [ " Juice " , " Water " , " Soda " , " Coffee " ];
07 var fruits = [ " Apples " , " Bananas " , " Grapes " , " Oranges " , " Strawberries " ];
08 var vegetables = [ " Broccoli " , " Carrots " , " Lettuce " , " Spinach " , " Tomatoes " ];
09 var meats = [ " Beef " , " Chicken " , " Pork " ];
10
11 function addVegetables() {
12 groceries = groceries.concat(vegetables);
13 }
14
15 function addFruits() {
16 groceries = groceries.concat(fruits);
17 }
18
19 function addOther() {
20 groceries.push(meats[1]);
21 groceries.push(dairy[3]);
22 }
23
24 fruits.shift();
25 addVegetables();
26
27 groceries.shift();
28 addFruits();
29
30 groceries.pop();
31 groceries.shift();
32
33 addOther();
34 document.getElementById( " list " ).innerHTML = groceries;
You need to debug the code on the left to determine how many items are in the groceries array at the specified breakpoints.
Evaluate the code and answer the questions by selecting the correct option from each drop-down list.
Note: You will receive partial credit for each correct answer.
Answer:
Explanation:
Explanation:
Line 26 drop-down: 5
Line 29 drop-down: 8
Line 32 drop-down: 6
The groceries array starts empty. Line 24 runs fruits.shift(), which removes " Apples " from the fruits array.
This leaves four fruits, but it does not add anything to groceries. Line 25 calls addVegetables(), which executes groceries = groceries.concat(vegetables);. Since vegetables contains five items, groceries contains 5 items at line 26. Line 27 then executes groceries.shift(), removing the first item from groceries and reducing the count to 4. Line 28 calls addFruits(), which appends the four remaining fruits, increasing the array count to 8; therefore, line 29 is 8. Line 30 executes groceries.pop(), removing the last item and reducing the count to
7. Line 31 executes groceries.shift(), removing the first item and reducing the count to 6. Therefore, line 32 is
6. The addOther() function on line 33 has not executed yet at the line 32 breakpoint. References/topics:

NEW QUESTION # 61
Which two CSS segments are valid filter properties? Choose 2.
Answer: A,C
Explanation:
The valid filter declarations are filter: opacity(25%) and filter: drop-shadow(16px 16px 16px red). The CSS filter property applies graphical effects to an element, commonly including image rendering effects such as blur, contrast, color shifts, transparency, and shadows. opacity(25%) is a valid filter function because filter opacity accepts a percentage or number to control the rendered transparency of the element. drop-shadow (16px 16px 16px red) is also valid because drop-shadow() is a CSS filter function, and MDN shows that it accepts two or three length values plus an optional color. box-shadow(...) is invalid in this context because box-shadow is a standalone CSS property, not a filter function; MDN explicitly distinguishes drop-shadow() from the box-shadow property. blur(25deg) is invalid because blur uses a length value such as pixels, not an angular value such as degrees. References/topics: CSS filter property, image effects, opacity filter, drop- shadow filter, valid filter-function syntax.
NEW QUESTION # 62
You write the following markup to create a page. Line numbers are included for reference only.
01 < !DOCTYPE html >
02 < html >
03 < head >
04 < style >
05
10 < /style >
11 < /head >
12 < body >
13 < svg height= " 500 " width= " 500 " >
14 < defs >
15 < filter id= " f2 " x= " 0 " y= " 0 " width= " 200% " height= " 200% " >
16 < feOffset result= " offOut " in= " SourceGraphic " dx= " 20 " dy= " 20 " / >
17 < feGaussianBlur result= " blurOut " in= " offOut " stdDeviation= " 10 " / >
18 < feBlend in= " SourceGraphic " in2= " blurOut " mode= " normal " / >
19 < /filter >
20 < /defs >
21 < text x= " 10 " y= " 100 " style= " fill:red; " > Blur Me! < /text >
22 Sorry, your browser does not support inline SVG.
23 < /svg >
24 < /body >
25 < /html >
An SVG blur filter is defined in the markup on the left. You need to apply the SVG blur filter to the text element on the page.
Which CSS code should you insert at line 05?
Answer: C
Explanation:
The correct CSS is option B because the SVG filter is declared inside < defs > with the identifier id= " f2 " .
To apply an SVG filter from CSS, the filter property must reference that filter by URL syntax using the filter' s ID selector: filter: url( " #f2 " );. The text selector targets the SVG < text > element, so the rule applies the defined filter effect to the visible text content, Blur Me!. The filter itself uses < feOffset > , < feGaussianBlur
> , and < feBlend > to create the blurred visual effect. Option A is incorrect because filter: #blur; is not valid filter-reference syntax and does not match the actual filter ID. Option C is incorrect because fill controls paint color, not filter application, and blur is not a valid fill value. Option D uses url(blur), which does not reference the defined f2 filter and omits the required ID reference.

NEW QUESTION # 63
You are creating the styling for your webpage. Which two CSS attributes produce a scroll bar if your content overflows its element? Choose 2.
Answer: B,C
Explanation:
The correct values are scroll and auto. The CSS overflow property controls what happens when content is too large to fit inside an element's box. MDN describes overflow as setting the desired behavior when content does not fit inside the element's padding box. The value overflow: scroll creates a scroll container and displays scrollbars so overflowing content can be reached, even when the scrollbar may not be strictly needed in some rendering environments. The value overflow: auto also creates scrolling behavior when content overflows, but it is conditional: scrollbars appear only when the content exceeds the available box size. hidden is incorrect because it clips overflowing content and hides the excess rather than exposing it through a scrollbar. visible is also incorrect because it allows overflow to render outside the element box and does not create a scroll container. Therefore, when the question asks which settings produce a scrollbar if content overflows, the precise answers are scroll and auto. References/topics: CSS overflow, scroll containers, overflow clipping, automatic scrollbars, layout flow.
