Question 1

Which of the following rules defines character encoding in every Cascading Style Sheets (CSS)document?
A) ​@charset="encoding"
B) ​@charset "encoding";
C) ​&char="encoding";
D) ​&char "encoding";

Accepted Answer

The correct syntax for defining character encoding in a CSS document is @charset followed by the encoding type in quotes, ending with a semicolon, as in `@charset "encoding";`.

Question 2

In the hexadecimal numbering system,the number 16 is expressed as _____.
A) ​1F
B) ​F
C) ​10
D) ​1

Accepted Answer

In hexadecimal system, the numbers go from 0 to F (which represents 10 to 15 in decimal). So, to express 16 in hexadecimal, you need to add another digit, which would be 1 followed by 0. Therefore, the correct answer is C) 10.

Question 3

_____ is the tint of a color and is usually represented by a direction on a color wheel.
A) ​Hue
B) ​Saturation
C) ​Lightness
D) ​Darkness

Accepted Answer

Hue refers to the base color itself without any tint or shade, essentially the position of the color on the color wheel.

Question 4

Yellow has the RGB triplet _____.
A) ​(0,0,0)
B) ​(255,255,0)
C) ​(0,255,255)
D) ​(255,0,255)

Accepted Answer

Yellow is a combination of green and red light, so it would have a high value for both the green and red components in the RGB triplet. B is the only choice with a high value (255) for both red and green, and a low value (0) for blue, which would result in a bright yellow color.

Question 5

Identify the correct syntax for adding comments in style sheets.
A) ​< !--comment-- >
B) ​/..comment
C) ​//comment//
D) ​/*comment*/

Accepted Answer

Comments in style sheets are denoted using /* comment */ syntax.

Question 6

Adding all the three primary colors-red,green,and blue-at maximum intensity produces the color _____,while adding any two of the three primary colors at maximum intensity produces the trio of complementary colors-yellow,magenta,and cyan.
A) ​white
B) ​blue
C) ​lime
D) ​black

Accepted Answer

Adding the three primary colors at maximum intensity produces white, which is the absence of any color. On the other hand, complementary colors are pairs of colors that, when combined, produce white. The three pairs of complementary colors are yellow and blue (producing green), magenta and green (producing red), and cyan and red (producing blue).

Question 7

Cascading Style Sheets (CSS)allow RGB values to be entered as _____.
A) ​binaries
B) ​hexadecimals
C) ​WYSIWYG values
D) ​RBG values

Accepted Answer

CSS allows RGB values to be entered as hexadecimal values, using six characters that represent the combination of the red, green, and blue values.

Question 8

The @import rule has the same impact as adding multiple _____ elements to a Hypertext Markup Language (HTML)file.
A) ​connection
B) ​link
C) ​contact
D) ​integrated

Accepted Answer

The @import rule is used in Cascading Style Sheets (CSS) to import a style sheet into another style sheet. This has the same impact as adding multiple <link> elements to an HTML file, which is used to link external resources, such as CSS style sheets, to an HTML document.

Question 9

_____ measures the intensity of the chosen color and ranges from 0% (no color)up to 100% (full color).
A) ​Hue
B) ​Saturation
C) ​Lightness
D) ​Darkness

Accepted Answer

Saturation measures the intensity of a color and ranges from 0% (no color) up to 100% (full color). Hue refers to the actual color itself, while lightness/darkness refers to the brightness of the color.

Question 10

The color scheme that uses two hues close to one another on the color wheel in which one color is the dominant color and the other is a supporting color used only for highlights and nuance is _____.
A) ​triad
B) ​tetrad
C) ​analogic
D) ​monochrome

Accepted Answer

The given color scheme is called an analogic scheme. It involves using two hues that are adjacent on the color wheel, with one color as the main or dominant color, and the other color as a supporting or accent color to add nuance and interest to the design. Monochrome uses a single hue with various shades and tones. Triad uses three colors on the wheel that are spaced evenly. Tetrad uses four colors that form two sets of complementary colors. Thus, the most appropriate answer is C.

Question 11

The _____ statement must always come before any other style rules in a style sheet.
A) ​@import
B) ​@embed
C) ​!import
D) ​!embed

Accepted Answer

The ​@import statement allows developers to include external style sheets within their main style sheet. This statement must always come before any other style rules in order to ensure that the external styles are properly incorporated.

Question 12

In the hexadecimal numbering system,the number 21 is expressed as _____.
A) ​1F
B) ​F
C) ​15
D) ​F1

Accepted Answer

In the hexadecimal numbering system, the number 21 in decimal is equivalent to 15 in hexadecimal (16^1 * 1 + 16^0 * 5).

Question 13

The Cascading Style Sheets (CSS)@rule that imports an external style sheet file located at ur1 is _____.
A) @import url(url);
B) @import "url";
C) @import prefix url
D) @import
Media
{
Url
}

Accepted Answer

The correct syntax for importing an external style sheet file using the @import rule is @import followed by the keyword "url" and the URL of the external file in parentheses. So, the correct answer is A) @import url(url);. Option B is incorrect because it uses quotation marks instead of parentheses. Option C is incorrect because "prefix" is not a valid keyword for the @import rule. Option D is incorrect because it uses the keyword "Media" followed by "Url," which is not a valid syntax for the @import rule.

Question 14

Graphic designers consider _____ easier to use because it allows them to set the initial color based on hue and then fine-tune the saturation and lightness values.
A) ​HTML
B) ​CSS
C) ​HSL
D) ​HTM

Accepted Answer

HSL (Hue, Saturation, Lightness) is the best choice for graphic designers as it allows them to set the initial color based on hue and then fine-tune the saturation and lightness values. HTML (HyperText Markup Language) and CSS (Cascading Style Sheets) are not color models, and HTM is not a valid choice as it is a typo.

Question 15

To set the foreground or text color of an element,use the following property:
A) ​text: color;
B) ​forecolor: color;
C) ​color: color;
D) ​backcolor: color;

Accepted Answer

The "color" property is used to set the foreground or the text color of an element in CSS. It specifies the color of the text content and can be set to any valid CSS color value. Option A, B, and D are not valid CSS properties for setting the foreground or text color of an element.

Question 16

A technique known as _____ places code conforming to older standards before newer properties,providing support for old browsers but still allowing newer standards and techniques to be used by the browsers that support them.
A) ​progressive enhancement
B) ​opacity enhancement
C) ​opacity enhancement.
D) ​pseudo-class structuring

Accepted Answer

This technique is known as progressive enhancement, where newer code is added on top of older code to provide support for older browsers while still allowing newer techniques for browsers that support them.

Question 17

Color values using the HSL model are described in Cascading Style Sheets (CSS)3 using _____.
A) ​#redgreenblue
B) ​rgb(number)
C) ​hsl (hue,saturation,lightness)
D) ​hsl (hue,shadow,lightness,opacity)

Accepted Answer

In CSS3, color values using the HSL model are described using the hsl(hue, saturation, lightness) function. The other options provided (#redgreenblue and rgb(number)) are not correct syntax for describing colors with the HSL model. Option D (hsl(hue, shadow, lightness, opacity)) is also incorrect syntax as there is no "shadow" parameter in the HSL model.

Question 18

_____ measures the brightness of a color and ranges from 0% (black)up to 100% (white).
A) ​Hue
B) ​Saturation
C) ​Lightness
D) ​Darkness

Accepted Answer

Lightness measures the brightness of a color and ranges from 0% (black) up to 100% (white).

Question 19

How is background color defined in a Cascaded Style Sheets (CSS)file?
A) ​@bgcolor "color";
B) ​@background="color";
C) ​background: color;
D) ​background-color: color;

Accepted Answer

The correct syntax for defining background color in a CSS file is using the "background-color" property followed by the desired color. Option A and B are invalid syntaxes while Option C is used to define the entire background, which includes the image, color and positioning.

Question 20

_____ defines how solid a color appears.
A) ​Clarity
B) ​Saturation
C) ​Lightness
D) ​Opacity

Accepted Answer

Opacity defines how solid a color appears, with higher opacity meaning less transparency and a more solid color appearance.
