How to format correctly for mobile viewport

Hi everyone, can somebody please help me with formatting for different viewport issues, the text seems to be mostly fine when I am viewing my site in the mobile viewport, but the images are all over the place. I am a newbie to webflow, I watched all sorts of tutorial videos about responsive design, so I know about the cascading effect from the desktop. Is there a something I can do so I don’t have to individually format everything single images on the different viewports?
Here is my read-only link, any help on this would be greatly appreciated!!!
