Hi,

The css-images spec defines how to determine the size of images. 
(css-lists should probably refer to it.)

http://dev.w3.org/csswg/css-images-3/#sizing

This involves a 'specified size' (which is not set for anonymous images 
in the 'content' property), the 'intrinsic size' of the image (gradients 
don’t have any) and the 'default size' which depends on the context, 1em 
by 1em for list markers.

If you’re also implementing css-images, the above actually determines 
the size of the "replaced CSS box". The size and position of the actual 
image inside that depend on the 'object-fit' and 'object-position' 
properties.
