IT Specialist HTML5 Application Development Sample Questions (Q17-Q22):

NEW QUESTION # 17
You need to use CSS to create the layout shown:

Review the layout shown on the left.
Complete the markup 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: display: grid;
Second blank: grid-template-columns: auto auto auto auto;
Third blank: grid-gap: 10px;
The layout shown is a CSS Grid layout with eight items arranged into four equal-width columns and two rows. The first required declaration is display: grid;, which turns the .grid-container element into a grid container. The second declaration is grid-template-columns: auto auto auto auto;, which defines four columns, matching the four visible boxes in each row: Mickey, Minnie, Luna, and George on the first row, then Bilbo, Bella, Madeline, and Groucho on the second row. The third declaration is grid-gap: 10px;, which creates spacing between the grid cells, matching the visible blue gaps around each item. The background-color:
#336699; creates the blue container background, while padding: 10px; adds space around the outer edge of the grid. The child rule .grid-container > div styles each grid item with a light background, centered text, padding, and larger font size.


NEW QUESTION # 18
Which JavaScript method is used to draw a circle on a canvas?

Answer: A

Explanation:
The correct method is arc(). In the Canvas 2D API, circles and circular arcs are drawn by creating an arc path on the canvas rendering context. MDN defines CanvasRenderingContext2D.arc() as creating a circular arc centered at (x, y) with a specified radius, start angle, end angle, and drawing direction. To draw a full circle, the common pattern is to call beginPath(), then arc(x, y, radius, 0, 2 * Math.PI), and then use stroke() or fill() to render the path. There is no standard Canvas 2D method named circle(), so option A is invalid. ellipse() can draw ellipses and can mathematically draw a circle if both radii are equal, but the classic and exam-targeted method for drawing a circle is arc(). bezierCurveTo() draws cubic Bezier curves and is used for custom curved paths, not the direct circle primitive. References/topics: Canvas 2D context, arc() method, drawing circles, radians, path rendering.


NEW QUESTION # 19
You are creating a form that requires the category to be entered as a two- or three-letter abbreviation. The input is mandatory.
You need to configure the input validation for the form.
Complete the markup by typing into the boxes.
Note: You will receive partial credit for each correct answer.

Answer:

Explanation:
minlength , maxlength , required
Explanation:
First box: minlength
Second box: maxlength
Third box: required
The correct validation attributes are minlength, maxlength, and required. The input must accept a category abbreviation that is either two or three characters long. The minlength= " 2 " attribute enforces the lower boundary by preventing submission when the entered text contains fewer than two characters. The maxlength= " 3 " attribute enforces the upper boundary by preventing the user from entering more than three characters into the field. Since the question states that the input is mandatory, the required attribute must also be included. required is a Boolean validation attribute, so it does not need a value; its presence alone makes the field required before the form can be submitted. Together, these attributes configure basic HTML5 constraint validation directly in markup without requiring JavaScript. The completed input therefore requires a value, rejects values shorter than two characters, and limits the value to no more than three characters.
References/topics: HTML5 form validation, minlength, maxlength, required, text input constraints, mandatory form fields.


NEW QUESTION # 20
The following two images show a web page that uses a responsive layout displayed on a mobile device and on a PC.
Displayed on a mobile device:

The layout stacks the content vertically.
Displayed on a computer monitor:
The layout displays the content cards horizontally in multiple columns.
Review the images on the left.
Complete the statements by selecting the correct option from each drop-down list.

Answer:

Explanation:

Explanation:
First drop-down: flex boxes
Second drop-down: background-size
Third drop-down: cover
The layout changes from a stacked mobile layout to a multi-column desktop layout without relying on media queries. That behavior is commonly achieved with responsive flex boxes, where items can wrap naturally based on the available width. The header image must fill the available header area on both mobile and desktop. For that requirement, the correct CSS property is background-size, and the correct value is cover.
background-size: cover scales the image so the entire header area is filled, even if part of the image is cropped. contain would preserve the full image but could leave empty space, and auto would keep the image at its natural size.


NEW QUESTION # 21
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.
