OOCSS (Object-Oriented CSS) is a CSS methodology that encourages the separation of the structure from the skin and the behavior from the structure. It promotes the creation of reusable, modular code by keeping styles independent of the HTML structure. This approach enhances maintainability and makes it easier to scale and update styles in a large codebase.

CSS minification primarily involves removing unnecessary whitespace and comments from the code. This results in a more compact file that can be transmitted faster over the network, contributing to improved page loading speed.

Utilizing shorthand properties in CSS allows developers to write concise and efficient code. This not only enhances code readability but also reduces the overall size of stylesheets, leading to quicker page loads.

While Bootstrap is a powerful CSS framework with a comprehensive set of styles and components, using it for a small project may introduce unnecessary overhead. The framework includes a wide range of styles, and if not all are used, it can result in larger file sizes, impacting performance. Developers should carefully consider the project's needs before opting for a comprehensive framework.

When dealing with a sidebar that needs to be fixed on desktop and static on mobile, the appropriate approach is using position: sticky with a value of top: 0 within a media query. This ensures the sidebar remains fixed on desktop but becomes static on mobile.

SMACSS emphasizes modular code organization, making it easier to scale, maintain, and reuse styles in large web applications.

The font-display property in CSS is crucial when using custom fonts as it determines how the font is displayed during the loading process. It allows developers to control the fallback behavior and enhance the user experience, especially when the custom font is still loading.

A key consideration for typography and character sets in CSS when considering internationalization is ensuring proper encoding and font support. This ensures that the content displays correctly for users across different languages and regions, avoiding issues with character rendering and readability.

The correct option is 2. The transform property with the scale function is used to resize elements, and a value of 2 doubles the size.

To create a shadow effect suggesting a top-right light source, you use positive values for the horizontal and vertical offsets in the box-shadow property. This casts a shadow to the bottom right, simulating light from the top right.
