How does the use of custom fonts affect the loading time of a web page?
- Decreases loading time by optimizing font rendering
- Depends on the browser's caching mechanism
- Increases loading time due to larger file sizes
- No impact on loading time
The use of custom fonts can increase the loading time of a web page because larger file sizes may need to be downloaded. This can affect the overall performance, especially on slower networks. Optimizing font files and using efficient formats can help mitigate this impact.
A developer is attempting to create a flexible layout where the widths of two columns (side-by-side) adapt to the viewport size while maintaining a gap between them without using any framework. Which combination of box model properties and units should they use to accomplish this?
- width: 50%, margin: auto;
- width: 50%, padding: 5px;
- flex-grow: 1, flex-shrink: 1, flex-basis: 50%;
- width: 50%, margin: 5%;
The correct combination is width: 50%, margin: 5%;. This ensures each column is 50% wide with a 5% margin, providing a gap. The other options either lack a gap, use padding instead of margin, or involve flex properties, which may not achieve the desired layout.
