Implicit grid sizing in Tailwind - Mini Project: Build & Apply

Create a Responsive Photo Gallery with Implicit Grid Sizing

📖 Scenario: You are building a simple photo gallery webpage. The gallery should automatically adjust the number of columns based on the screen size, without explicitly setting the number of columns. This means the grid will create as many columns as fit, each with a minimum width, using implicit grid sizing.

🎯 Goal: Build a responsive photo gallery using Tailwind CSS that uses implicit grid sizing. The gallery should have a grid container that automatically creates columns with a minimum width of 12rem and fills the available space. Each photo is a square with a border and some spacing.

📋 What You'll Learn

Create a grid container using Tailwind CSS classes

Use implicit grid sizing with grid-cols-[repeat(auto-fill,minmax(12rem,1fr))]

Add at least 6 photo items inside the grid container

Each photo item should have a fixed aspect ratio (square), border, and margin

The gallery should be responsive and adjust columns automatically on different screen sizes

💡 Why This Matters

🌍 Real World

Photo galleries are common on websites for portfolios, e-commerce, and social media. Using implicit grid sizing helps create flexible layouts that adapt to different screen sizes without manual column counts.
