Nancy, I know that Design View ist NOT a browser.
Independent of that the intended functionality of the design view is, that CSS is interpreted in the Design View.
At the moment nobody likes to confirm, that "height: auto" is ignored in the Design View. It's OK. But it would be helpful for the discussion, when someone could confirm that.
Thanks for your suggestion, I really appreciate, that you like to help me.
But I do not want to set a width to figure, but to img.
Your wrote "AUTO does not change the height of your image."
That is not true.
When you use my complete code of the last posting in a browser, you get an automatically calculated height. Depending on 1em. That is the intended function of the value "auto".
I do not say anymore, that that does not work in Design View.
You say, that I my understanding of the value is not correct.
Design view is a throwback to the old Macromedia days and is NOT capable of interpreting advanced CSS level 2 and level 3 specs. That's why Live view was created. Use them both or not, your choice.
See screenshots below.

Same code in Live view:

I can give you lots of other examples where CSS rendering is hideous or ignored in Design view.
