image resizing in browser

I came across a comprehensive article on image resizing. I found several points interesting:

• Specifying both width and height on an image in css will lose its aspect ratio
• Specifying width and height: auto will keep its aspect ratio
• Specifying width: 100% might scale the image up to fit parent width
• Specifying max-width: 100% will scale image down to fit parent width but never up

Yet to try object-fit and object-position CSS properties.

Avoid client side resizing and serve correctly sized images from server

I think the appropriate solution will differ from use case to use case. Actual image and then thumbnail sizes, for example. Then again there's img srcset which I have yet to try out as well.

Ooo, much to explore.
