Question 1/15

Which of the following is NOT a valid value for the animation-direction property in CSS?

The animation-direction property in CSS sets the direction of an animation when it cycles back to the beginning. The valid values for this property are normal, reverse, alternate, and alternate-reverse. slide is not a valid value for this property.

Question 2/15

Which of the following is NOT a valid value for the animation-timing-function property in CSS?

The animation-timing-function property in CSS sets the easing of an animation. The valid values for this property are ease, linear, ease-in, ease-out, ease-in-out, step-start, step-end, steps(), and cubic-bezier(). bounce is not a valid value for this property.

Question 3/15

Which of the following is a valid value for the object-fit property in CSS?

The object-fit property in CSS specifies how an element should fit inside its container. The valid values for this property are fill, contain, cover, none, and scale-down. Additionally, stretch is also a valid value, which scales the image to fit both the height and width of the container.

Question 4/15

What will the following code produce?
.element {
  box-shadow: 5px 5px 5px rgba(0, 0, 0, 0.5);
}

The box-shadow property sets a shadow effect on an element, using the syntax x-offset y-offset blur spread color. In this case, the x-offset and y-offset values are both 5 pixels, which means the shadow will appear 5 pixels to the right and 5 pixels below the box. The blur value sets the amount of blur applied to the shadow, while the spread value sets the size of the shadow. The color of the shadow is set to black, with an opacity of 50%, specified using the rgba() function.

Question 5/15

Which of the following selectors has the highest specificity in CSS?

Specificity in CSS determines which styles will take precedence when multiple styles apply to an element. The higher the specificity, the more priority a style has. The specificity of a selector is determined by the number of ID selectors, class selectors, and element selectors it contains. An ID selector has the highest specificity, followed by class selectors, element selectors, and universal selectors.

Question 6/15

Which of the following is NOT a valid value for the display property in CSS?

The display property in CSS sets the display behavior of an element. The valid values for this property are block, inline, inline-block, none, table, table-row, table-cell, and list-item. flexbox is not a valid value for this property, but flex is a valid value for the display property when used to enable flexbox layout.

Question 7/15

Which of the following is a valid value for the backdrop-filter property in CSS?

The backdrop-filter property in CSS applies a filter effect to the area behind an element, creating a blur or other visual effect. The valid values for this property include blur, brightness, contrast, grayscale, hue-rotate, invert, opacity, saturate, sepia, and drop-shadow. All of the options listed in the question are valid values for this property.

Question 8/15

What will the following code produce?
.element {
  transition: all 1s ease-in-out;
}

.element:hover {
  transform: rotate(360deg);
}

The transition property sets a transition effect on an element, which in this case is set to all to apply the transition to all properties, with a duration of 1 second and easing set to ease-in-out. When the element is hovered over, the transform property is used to rotate the element 360 degrees. Because the transition property is set on the element, the rotation will be animated over the duration of 1 second with easing in and out, giving a smooth effect.

Question 9/15

What will the following code produce?
.container {
  display: grid;
  grid-template-columns: repeat(3, 1fr);
  grid-template-rows: 100px auto 100px;
  grid-gap: 10px;
}

The display: grid property turns an element into a grid container. The grid-template-columns property defines the columns of the grid, using the repeat() function to create three columns of equal width, each with a 1fr unit. The grid-template-rows property defines the rows of the grid, with the first and third rows set to a fixed height of 100 pixels, and the second row set to auto, which will take up the remaining available space. The grid-gap property sets a gap of 10 pixels between grid cells.

Question 10/15

What will the following code produce?
h1 {
  font-size: 3rem;
  line-height: 1.2;
  margin: 0;
  padding: 1rem;
  background-color: #333;
  color: #fff;
  text-shadow: 1px 1px 2px rgba(0,0,0,0.5);
}

The font-size property sets the size of the heading to 3 rem, which is a large size. The line-height property sets the line height to 1.2, which provides adequate space between lines of text. The margin property sets the margin of the heading to 0, which removes any spacing around the heading. The padding property adds 1 rem of padding around the heading. The background-color property sets the background color of the heading to a dark gray. The color property sets the text color to white, which provides good contrast against the dark background. Finally, the text-shadow property adds a subtle shadow to the text, which enhances readability.

Question 11/15

Which of the following is a valid value for the text-overflow property in CSS?

The text-overflow property in CSS specifies how overflowed content that is not displayed should be signaled to the user. The valid values for this property are clip, ellipsis, and fade. clip hides overflowed content, ellipsis displays an ellipsis (...) to indicate that content has been cut off, and fade fades out overflowed content. All of the options listed in the question are valid values for this property.

Question 12/15

Which of the following is a valid value for the text-orientation property in CSS?

The text-orientation property in CSS specifies the orientation of the text in a block container. The valid values for this property are mixed, upright, sideways, sideways-right, and sideways-left. All of the options listed in the question are valid values for this property.

Question 13/15

Which of the following is NOT a valid value for the text-decoration property in CSS?

The text-decoration property in CSS sets the decoration of text, such as underlines, overlines, and line-throughs. The valid values for this property are none, underline, overline, line-through, and underline overline. strike-through is not a valid value for this property.

Question 14/15

Which of the following is NOT a valid value for the border-style property in CSS?

The border-style property in CSS sets the style of a border on an element. The valid values for this property are none, hidden, dotted, dashed, solid, double, groove, ridge, inset, and outset. gradient is not a valid value for this property.

Question 15/15

What will the following code produce?
.element {
  animation-name: pulse;
  animation-duration: 2s;
  animation-timing-function: ease-in-out;
  animation-iteration-count: infinite;
}

@keyframes pulse {
  0% {
    transform: scale(1);
  }
  50% {
    transform: scale(1.1);
  }
  100% {
    transform: scale(1);
  }
}

The animation-name property sets the name of the animation, which in this case is pulse, defined in the @keyframes rule. The animation-duration property sets the duration of the animation to 2 seconds, while animation-timing-function sets the easing to ease-in-out. The animation-iteration-count property sets the animation to repeat infinitely.

The @keyframes rule defines the pulse animation, which uses three keyframes to define the animation over time. At 0% (the start of the animation), the element is at its original size of 1. At 50%, the element is scaled up to 1.1, creating a pulsating effect. At 100% (the end of the animation), the element returns to its original size of 1. The result is a text element that pulsates between 110% and 100% of its original size, with a duration of 2 seconds, easing in and out, and repeating infinitely.
