@Doug, you might need to tidy up your static page(s) HTML. Paragraphs and unordered lists etc. should wrap fine, unless the HTML is badly formatted, or there's missing closing HTML tags etc.
The responsive class "img-fluid" is automatically added to all images, so they shouldn't cause any issues.
There's also a small utility available that lists any elements that 'spill outside' of the current viewport to the browser console.
Near the bottom of /skin/reboot/js/reboot.js
Set...
Code:
var showOCElems = false;
To...
Code:
var showOCElems = true;
Then refresh the page and check your browser console. You may need to clear the template cache.
