What is a good starting point for handling responsive images?
- Page Owner: Not Set
- Last Reviewed: 2022-04-12
Optimizing images is deceptively complicated. Different image sizes, cropping, pixel densities, etc. What do I need to consider, and who handles the various pieces of the puzzle?
Answer
Here is an outline of the things to consider and a baseline approach to handling responsive images:
TLDR:
Consider:
Optimizing the image size to fit the layout and screen resolution
Using next-generation image formats (ex: .webp) with fallbacks
Switching images based on layout needs (editor control over cropping/different aspect ratio/dark mode)
