D A server-side technology
Explanation: The viewport is the visible area of a web page in the browser window that users can see without scrolling.
A viewport-width
B width and height
C content
D zoom
Explanation: The CSS width and height properties can be used to set the viewport dimensions, though they're typically controlled via the viewport meta tag.
A Sets the zoom level when the page first loads
B Sets the initial screen width
C Sets the page title
D Sets the language
Explanation: The initial-scale attribute controls the zoom level when the page first loads on a mobile device.

Explanation: Flexbox's ability to make items grow and shrink to fill available space makes it ideal for responsive layouts.
A Designing for mobile only
B Starting with the mobile design and scaling up to larger screens
C Using mobile-specific HTML
D Ignoring desktop users
Explanation: The mobile-first approach starts with designing for mobile screens and then adding enhancements for larger screens, rather than designing for desktop and scaling down.
A Using fixed-width images
B Using SVG images
C Using max-width: 100%
D Using height: 100%
Explanation: Using max-width: 100% on images is a fundamental responsive image technique that ensures images scale within their containers.
A They are faster to write
B They automatically adjust to the user's screen size and settings
C They are more colorful
D They work in all browsers

B Clamps a value between a minimum and maximum range
C Creates a clamping effect
D Removes CSS properties
Explanation: The clamp() function restricts a value between a defined minimum, preferred, and maximum value, making it ideal for responsive values.
A To target screens larger than a specific width
B To target screens smaller than a specific width
C To target exactly a specific width
D To target all screens
Explanation: The min-width media query targets screens that are larger than or equal to the specified width, typically used in mobile-first designs.
A To target screens larger than a specific width
B To target screens smaller than or equal to a specific width
C To target exactly a specific width
D To target all screens
Explanation: The max-width media query targets screens that are smaller than or equal to the specified width, typically used in desktop-first designs.
