Please take a quick look at this webpage:
http://fbatdesign.xyz/markdownpreviewer/markdownpreviewer.html
Notice how the output extends beyond the white box labelled Preview. I would like the Preview output to always be displayed against a white background. I created a div and gave it a size and border so that the output would be in it. But it appears the innerHTML is not bound by the div that surrounds it.
I would either like to make my preview box height match the output size, or I would like the output to be kept inside the current box with scrollbars.
Can someone suggest how I can do either of these? Thanks.
