CSS Testing tips

🧪

For testing image grids: generate images of varied aspect ratios (square, portrait, wide). See if your CSS handles them.

💡

For testing very tall or wide images: use the custom dimensions to make absurd aspects like 100×1000 or 2000×100.

🎯

Enable "Show diagonals" to visually verify alignment and crops at different sizes.
