I really like how it looks on the mobile version but it is too big for the desktop version. If I try to modify the size of the images from the theme settings (by setting them on medium), it becomes good for the desktop version but really bad for the mobile version. Can I modify the size of them only for the desktop version? Thanks in advance
This is likely a CSS fix.
If you can, post your website’s URL and the theme you’re using, we might be able to give you a more detailed fix.
