The method
Use `grid-template-columns: repeat(auto-fit, minmax(min-width, 1fr))` to create galleries where images responsively fill the container. Adjust `min-width` to control image size. Test on multiple screen sizes for optimal layout.
The prompts
Prompt 1
Simulate a scenario: I'm building a photography portfolio website and want to display my images in a grid layout that adapts to different screen sizes. The images should automatically resize and reflow to fill the available space without cropping. My current code has a fixed number of columns, which doesn't work well on mobile. Generate the necessary CSS code using CSS Grid's `auto-fit` and `minmax` functions to achieve this responsive behavior. Explain how the values you used affect the layout.
Prompt 2
Assume I'm developing an e-commerce site and need to create a product gallery. Each product image should be displayed in a grid. I want at least three products to fit in a row on larger screens, but on smaller screens, the products should stack vertically. Write CSS code using `grid-template-columns: repeat(auto-fit, minmax(minimum_size, 1fr));` to create a flexible gallery. Explain the role of `minimum_size` in controlling the layout's responsiveness. Provide a range of suitable `minimum_size` values based on typical product image dimensions and screen sizes, along with justifications.
