1013510136
10137+ <div class=issue>
10138+ <p>In cases where an explicit width or height is set and the other
10139+ dimension is auto, applying a minimum or maximum constraint on the
10140+ auto side can cause a conflict between honoring the explicit dimension
10141+ and honoring the (implicit) aspect ratio. The Working Group is split
10142+ on how best to resolve the issue: should the result be as close as
10143+ possible to (but not necessarily) preserving the aspect ratio while
10144+ always honoring explicit widths and heights, or should the result be
10145+ as close as possible to (but not necessarily) honoring the explicit
10146+ dimension while always honoring the aspect ratio?
10147+
10148+ <p>Here is an example of the scenario in mind: A 1:1 image is given
10149+ the following style declarations;
10150+
10151+ <pre>width: 200px; min-height: 300px;</pre>
10152+
10153+ <p>If we honor the width over the aspect ratio, the image winds up
10154+ 200px width by 300px height. If we honor the aspect ratio over the
10155+ width, the image winds up 300px width by 300px height.
10156+
10157+ <p>This draft specifies the former behavior. We are not yet committed
10158+ either way, and would appreciate feedback from the authoring community
10159+ on this issue.
