Conditionally add css class?

[mark-chief]

Hello, is there way to conditionally add a class to an image based on a set width?

E.g if image width is larger than container div 640px wide then add class="img-fluid".

Context behind this is to ensure that images in a redactor field scale to fit their container size. but only images that are too big.

Thanks

Nope, sorry. That would require some kind of closure support in order to evaluate each node/image, which Retcon currently doesn't have.
