Foundation Interview Questions and Answers

1. What is the Foundation framework?

   • Answer: Foundation is a responsive front-end framework created by ZURB. It's a collection of CSS, JavaScript, and HTML components and templates that help developers build responsive and aesthetically pleasing websites and web applications quickly and efficiently.

2. What are the key features of Foundation?

   • Answer: Key features include responsive grid system, pre-built UI components (buttons, forms, navigation), a robust Sass framework, extensive documentation, and a large and active community.

3. How does Foundation's responsive grid system work?

   • Answer: Foundation uses a flexible grid system based on classes and media queries. You define the number of columns you want within a row using classes like `small-12`, `medium-6`, `large-4`, etc., which adjust column widths based on screen size. Media queries ensure the layout adapts gracefully to different devices.

4. Explain the difference between `small-`, `medium-`, `large-`, and `xlarge-` classes in Foundation's grid system.

   • Answer: These classes specify the number of columns an element should occupy at different breakpoint sizes. `small-` applies to the smallest screens, `medium-` to slightly larger screens, `large-` to larger desktops, and `xlarge-` to extra-large screens. The numbers following these prefixes (e.g., `small-6`) indicate the number of columns out of the total number of columns in a row.

5. How do you include Foundation in your project?
