How To Enable Auto Aspect Ratio?

I too am looking for guidance with this. Anyone have any css tips? Using Brine (personally).

You won't find a CSS solution for this because Squarespace use JavaScript to determine the way that the images appear. 

If the lack of an 'auto' ratio is an issue for you, please submit a feature request to Squarespace by raising a ticket through Customer Care. They'll document your feedback and share it with the appropriate team. They do not monitor this forum for product feature requests
 

Thanks Paul for your comments. I have hit exactly this issue with a client who is asking me why all of his images have to be either landscape or portrait. He's selling furniture and some are tall and some are wide and he doesn't have a large warehouse to take clean photos in at the moment. Can someone let me know if they have submitted a feature request. If not, I'll do it. 

Feature requests drive priorities so the more requests they receive, the better the chances that they will recognise this pain point and fix it for us 😀
