to make the images scale with the users screen/window/port use "percentage" in the image properties instead of "pixels".
right now you can see the difference between the top picture, which doesn't autoscale, and the green smoke picture and chart which do scale when you change your browser window size.
the online editor will strip out most other html and or stylesheet stuff so we're pretty limited on what autosizing tricks we can do, like for making it autosize to a phone screen.
""<meta name="viewport" content="width=device-width, initial-scale=1.0">""
that would work if the editor didn't strip it out.
