IT Specialist HTML5 Application Development Sample Questions (Q46-Q51):

NEW QUESTION # 46
You are drawing on the canvas defined by the white square.

At which x, y coordinate is the upper-left corner of the filled square?

Answer: C

Explanation:
The correct coordinate is 50,50. In an HTML5 canvas, the coordinate system begins at the upper-left corner of the canvas. The x-coordinate increases as you move to the right, and the y-coordinate increases as you move downward. Therefore, 0,0 represents the top-left corner of the entire white canvas area. In the displayed image, the filled black square is not positioned at the top-left edge, top-center, or left-center of the canvas.
Instead, its upper-left corner is offset both horizontally and vertically from the origin. Among the available choices, 50,50 is the only coordinate that moves the square 50 units to the right and 50 units down from the canvas origin. This matches the visual placement of the filled square inside the white canvas. Option A would place the square at the canvas origin. Option B would place it along the left side, halfway down. Option C would place it along the top edge, halfway across. References/topics: HTML5 canvas coordinate system, x/y positioning, drawing rectangles, fillRect(x, y, width, height).


NEW QUESTION # 47
You are creating a form that asks a user to enter their phone number. The form must be submitted only if the phone number field is not empty and matches the format 111-444-7777. Which markup should you use?

Answer: C

Explanation:
The correct markup is option D. The type= " tel " input type is appropriate for telephone-number entry, but it does not automatically validate a specific telephone-number format because phone formats vary internationally. MDN notes that tel inputs allow telephone entry but are not automatically validated to a particular format. Therefore, a pattern attribute is required to enforce the exact structure. The regular expression [0-9]{3}-[0-9] {3}-[0-9]{4} requires three digits, a hyphen, three digits, another hyphen, and four digits, matching the requested format such as 111-444-7777. MDN defines the pattern attribute as a regular expression the input value must match for constraint validation. The required attribute is also necessary because the field must not be empty; MDN states that required indicates the user must specify a value before the form can be submitted. Option A only limits length. Option B lacks hyphen validation and required.
Option C hard-codes only specific digits. References/topics: HTML5 validation, tel, pattern, required, regular expressions.


NEW QUESTION # 48
The following output has more text than will fit in the element.

You need to apply CSS to contain the text inside the element ' s border without creating unneeded scrollbars or losing text. Which attribute setting should you use?

Answer: C

Explanation:
The correct setting is overflow: auto;. The CSS overflow property controls how content behaves when it does not fit inside an element's padding box. The requirement has three parts: keep the text inside the element's border, avoid unnecessary scrollbars, and avoid losing text. overflow: hidden clips overflowing content and does not provide a user-visible scrollbar, so text can become inaccessible. overflow: visible allows excess content to render outside the element's box, failing the containment requirement. overflow: scroll makes the element scrollable, but user agents display scrollbars whether or not content is actually overflowing, which violates the requirement to avoid unneeded scrollbars. MDN describes overflow: auto as clipping overflow content at the padding box while allowing it to be scrolled into view, with scrollbars displayed only when content is actually overflowing. This makes auto the precise choice for a controlled text container. References
/topics: CSS overflow, scroll containers, content clipping, layout flow, preserving overflowing content.


NEW QUESTION # 49
Which element should you use to rotate an SVG square?

Answer: A

Explanation:
The correct element is animateTransform. In SVG, rotation is not produced by drawing a different shape; it is produced by applying a transformation to an existing graphical element, such as a < rect > representing a square. The < animateTransform > element is specifically designed to animate the transform attribute of a target SVG element, and its supported transformation types include translation, scaling, rotation, and skewing.
Therefore, to rotate a square, the square would normally be defined with a shape element such as < rect > , and an < animateTransform > child or associated animation would specify attributeName= " transform " and type= " rotate " . animateMotion is incorrect because it moves an element along a motion path rather than rotating the element itself. circle is a shape element, not an animation mechanism. path defines arbitrary vector geometry, but it does not by itself animate or rotate another object. References/topics: SVG graphics, SVG transformations, animation elements, transform attribute, rotation animation.


NEW QUESTION # 50
Review the markup segment. Which entry will validate successfully according to the required pattern?

Answer: D

Explanation:
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.
