________ is a technique in CSS where multiple images are combined into a single image to reduce the number of server requests.
- CSS Sprites

CSS Sprites is a technique where multiple images are combined into a single image, reducing server requests and improving performance.
In a Flexbox layout, how can you ensure that some items take up more space than others, depending on the available space?
- Apply flex-basis: 200px; to the items requiring more space.
- Set flex-grow: 2; on the items that should take up more space.
- Use the order property to prioritize the larger items.
- Utilize flex: 2; on the items needing extra space.
To make certain items take up more space in a Flexbox layout, use the flex-grow property. By assigning a higher value to flex-grow, you instruct the container to allocate more space proportionally to items with higher values, based on the available space.
In Tailwind CSS, how does the approach of "utility-first" differ from traditional CSS frameworks like Bootstrap?
- Utilizes a large set of single-purpose utility classes that directly apply styles in the HTML, promoting flexibility and customization.
- Uses predefined components and a fixed set of class names for styling, limiting customization.
- Tailwind and Bootstrap follow the same "utility-first" approach.
- Tailwind only supports utility classes for typography, not for layout and spacing.
Tailwind CSS embraces a "utility-first" approach, offering a vast set of single-purpose utility classes that can be applied directly in the HTML. This approach provides flexibility and allows developers to customize styles efficiently. In contrast, traditional frameworks like Bootstrap rely on predefined components with fixed class names, which can limit customization options.
Bootstrap and Tailwind are examples of what kind of tools in web development?
- CSS preprocessors
- Front-end frameworks
- JavaScript frameworks
- Server-side scripting tools
Bootstrap and Tailwind are popular front-end frameworks that provide pre-designed components and styles, simplifying the development of responsive and visually appealing web interfaces.
The concept of ___________ involves identifying and prioritizing the rendering of only the necessary CSS needed for the above-the-fold content.
- Browser Rendering Engine
- Critical Rendering Path
- Lazy Loading
- Progressive Rendering
The Critical Rendering Path is the sequence of steps the browser goes through to convert the HTML, CSS, and JavaScript into pixels on the screen. Critical CSS is the CSS required for rendering above-the-fold content, and optimizing it is crucial for faster page loads.
In a box shadow declaration, what does the 'blur radius' value control?
- Distance of the shadow
- Fuzziness of the shadow edges
- Size of the shadow
- Spread of the shadow
The 'blur radius' value in a box shadow declaration controls the fuzziness or softness of the shadow edges. A higher blur radius results in a more diffused shadow.
When designing a web page, if a developer wants to create a realistic button with a press-down effect on click, which combination of box shadow properties should they manipulate?
- box-shadow: 2px 2px 4px 0px rgba(0, 0, 0, 0.5), inset 0 0 10px rgba(0, 0, 0, 0.5);
- box-shadow: 0px 2px 4px 0px rgba(0, 0, 0, 0.5), inset 0 0 10px rgba(0, 0, 0, 0.5);
- box-shadow: 0 2px 4px rgba(0, 0, 0, 0.5), inset 0 0 10px rgba(0, 0, 0, 0.5);
- box-shadow: 0 0 10px rgba(0, 0, 0, 0.5), inset 0 0 4px rgba(0, 0, 0, 0.5);
The correct combination is option 1. This creates a box shadow with an inset effect, simulating a button press-down effect.
In a scenario where you need to create an overlay that makes the underlying content partially visible, which combination of gradient and opacity would be most effective?
- linear-gradient(rgba(0, 0, 0, 0.8), rgba(0, 0, 0, 0.5))
- linear-gradient(rgba(255, 255, 255, 0.5), rgba(255, 255, 255, 0.8))
- radial-gradient(rgba(0, 0, 0, 0.5), rgba(0, 0, 0, 0.8))
- radial-gradient(rgba(255, 255, 255, 0.8), rgba(255, 255, 255, 0.5))
The combination linear-gradient(rgba(255, 255, 255, 0.5), rgba(255, 255, 255, 0.8)) creates an effective overlay, blending transparency and visibility.
In CSS, how does the ::after pseudo-element differ from the :after pseudo-class in terms of functionality and use?
- ::after is used for creating new DOM elements.
- ::after is used for styling elements based on content.
- :after is used for adding content after an element.
- :after is used for styling elements based on states.
The ::after pseudo-element in CSS is used for styling elements based on their content, while the :after pseudo-class is used for adding content after an element. Understanding this difference is crucial for effective use in styling.
