Hi,

I would like to get a clarification on having "auto" value for one dimension in background-size property.

As per the specification http://www.w3.org/TR/css3-background/#background-size, an ‘auto’ value for one dimension is resolved by using the image's intrinsic ratio and the size of the other dimension, or failing that, using the image's intrinsic size, or failing that, treating it as 100%.

Assume that  background-size is specified as "auto 8px" and the background-image used is of intrinsic size (2,32). Assume that the UA takes 'integer' for width, then the width of the background image using intrinsic-ratio computes to 0 {(2/32) * 8 = 0.5, which is rounded to 0 as UA takes only integer for width}

Does computing the width to 0 using intrinsic ratio can be considered as a failure? What are the various types of failures that can happen while resolving the dimension using intrinsic ratio?

Thanks,
