- 'container' has a transparent background, 'container-fluid' has a colored background
- 'container' is for text-only, 'container-fluid' is for images

The technique of 'lazy loading' is primarily used to optimize ___ on a webpage.
- Memory Usage
- Loading Time
- Script Execution
- Network Bandwidth
Lazy loading is a strategy used to optimize loading time on a webpage. It defers the loading of non-essential resources, improving initial page load performance.
Bootstrap's responsive utility classes include '.d-___-none' to control visibility.
- xs
- sm
- lg
- xl
Bootstrap's responsive utility classes use prefixes like '.d-xs-none,' '.d-sm-none,' etc. The correct option is 'lg,' representing large screens. These classes are handy for managing visibility on specific screen sizes in a responsive design.

Discuss the advantages of using SASS variables for Bootstrap theme customization.
- Allows for easy and centralized color scheme changes
- Improves maintainability by avoiding hard-coded values
- Facilitates collaboration among developers
- Reduces file size by eliminating redundant values
SASS variables in Bootstrap make it convenient to change the entire color scheme by modifying a few variables. This improves maintainability, promotes collaboration, and doesn't necessarily reduce file size but enhances readability and consistency.
