Which of the following Viewport Property sets the initial scaling factor?

scale
initial-scale
minimum-scale
user-scale

The correct answer is: B. initial-scale

The initial-scale property sets the initial scaling factor of the viewport. It is a CSS property that takes a number as its value. The number represents the initial scaling factor of the viewport, which is the ratio of the viewport’s width and height to the width and height of the document.

The initial-scale property can be used to set the initial scaling factor of the viewport to a specific value, or it can be used to set the initial scaling factor of the viewport to a value that is based on the user’s screen size.

For example, the following CSS code sets the initial scaling factor of the viewport to 1.0:

css
html, body {
width: 100%;
height: 100%;
initial-scale: 1.0;
}

The following CSS code sets the initial scaling factor of the viewport to 0.5 on devices with a screen width of less than 600 pixels:

css
html, body {
width: 100%;
height: 100%;
initial-scale: 0.5;
}
@media screen and (max-width: 600px) {
initial-scale: 1.0;
}

The initial-scale property is a very important property for responsive web design. It allows you to control the initial size of the viewport on different devices, which ensures that your website looks good on all devices.

  • A. scale The scale property is a CSS property that takes a number as its value. The number represents the scaling factor of the viewport, which is the ratio of the viewport’s width and height to the width and height of the document.

  • C. minimum-scale The minimum-scale property is a CSS property that takes a number as its value. The number represents the minimum scaling factor of the viewport. The minimum-scale property can be used to prevent the viewport from being scaled below a certain size.
  • D. user-scale The user-scale property is a CSS property that takes a number as its value. The number represents the user’s preferred scaling factor of the viewport. The user-scale property can be used to allow the user to scale the viewport to a size that they prefer.
