CSS: 100% width or height while keeping aspect ratio?

Question

Currently, with STYLE, I can use width: 100% and auto on the height (or vice versa), but I still can\'t constrain the image into a specific positio

Answer 1

Use JQuery or so, as CSS is a general misconception (the countless questions and discussions here about simple design goals show that).

It is not possible with CSS to do what you seem to wish: image shall have width of 100%, but if this width results in a height that is too large, a max-height shall apply - and of course the correct proportions shall be preserved.
