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.
To optimize performance, Bootstrap recommends using 'transform' and 'opacity' properties for animations because they do not trigger ___.
- Layout reflows
- Browser repaints
- Forced synchronous layouts
- GPU acceleration
In Bootstrap, using 'transform' and 'opacity' properties is recommended for animations as they trigger GPU acceleration, which improves performance by offloading the animations to the GPU. This avoids layout reflows, which are resource-intensive and can cause performance bottlenecks.

The technique of 'lazy loading' is primarily used to optimize ___ on a webpage.
- Memory Usage
- Loading Time
- Script Execution
- Network Bandwidth
