Avada. Featured image does not resize small enough

The featured image on my main page resizes with browser size, but stops getting smaller at some point. I can’t find a way to make it keep getting smaller. Thank for your help.

Hello Steve,

If you have problems with your purchased item, I strongly recommend you to contact the author for bugfix support. In this case to reach the author of Avada theme please access this url:

P.S: You can also regenerate all images sizes using a plugin like Regenerate Thumbnails. It should be ok after regenerating the sizes;

Have an wonderful day!
